Notes

1. Chapter went inactive during the Civil War was not reformed until 1892.
2. After the Alpha chapter at Miami University went inactive, the title of Alpha or Parent chapter was transferred to Gamma chapter at the fraternity's second convention on April 27, 1859. When the Miami chapter was revived in 1892, the Alpha title was restored to it.
3. After going inactive, the chapter was reformed in 1926 from Sigma Phi (local), established in 1926.
4. Jefferson College merged with Washington College to form Washington & Jefferson College in 1865. When the Jefferson campus was closed in 1869, many of the chapter's members transferred to other institutions, leading to the Jefferson chapter going inactive.
5. The chapter at the University of Virginia was originally called Rho. It went inactive during the Civil War and, by the time it reformed in 1866, the name Rho had been reassigned to a new chapter at Butler University. As a result, the Virginia chapter was reinstalled with the name Gamma in 1866; that name was available because Gamma (Original) had become Alpha (Second). However, the Virginia name was changed to Psi at the fraternity's sixth grand chapter meeting in 1866.
6. The chapter formed at Pennsylvania College, which became Gettysburg College in 1921. It absorbed the Theta chapter of Upsilon Beta on February 3, 1874.
7. Chapter formed from Iota Society, established in 1861.
8. The chapter was suspended by Sigma Chi in 1972 after being on probation for several years. However, it was reinstated in 1973.
9. In February 1966, Phi chapter notified Sigma Chi that it was withdrawing and returning its charter; the fraternity declared the chapter inactive on January 21, 1967. This action resulted from the Sigma Chi grand council's denial of a pledge born in Hawaii but of Korean ancestry. Because discriminatory practices were against the policies of Lafayette College, the college indicated it would ban Sigma Chi from its campus if the initiation did not proceed. The chapter's members and alumni decided to move forward as a local fraternity called Sigma Phi Chi.
10. Chapter formed from Kappa Phi Lambda, established in 1865. Later, it absorbed Eclectic.
11. After going inactive, the chapter was reformed in 1936 from Alpha Delta Alpha (local), established in 1928.
12. After going inactive, the chapter was reformed in 1931 from Phi Sigma Epsilon (local), established in 1926. The Sigma Chi executive committee suspended the chapter in 1972, after first placing it on probation and alumni supervision without achieving the desired level of compliance.
13. After going inactive, the chapter was reformed in 1923 from Delta Delta (local), established in 1913.
14. Chapter formed at Howard College, which was renamed Samford in 1965.
15. After going inactive, the chapter reformed in 1910 from U.P.L. (local), established in 1894.
16. The Wooster chapter's successor on campus was Tri-Kapp (local, 1913 to 1965). Due to the negativity associated with those Greek letters, this group was renamed Kappa Chi (local, 1965 to 2005), with a later faction splitting to form Omega Alpha Tau (local, 1976 to c. 1995). As is the Wooster practice, these local fraternities called themselves with 'section' monikers, in this case, "VII Section". See List of fraternities and sororities at the College of Wooster.
17. After going inactive, the chapter was reformed in 1914 from Phi Epsilon (local), established in 1913.
18. The chapter at the University of Michigan was originally chartered as Psi Psi. After going inactive, Psi Psi chapter was reformed as Theta Theta because its former name had been reassigned to a chapter at Syracuse University.
19. The chapter was formed at Southern University in Greensboro, Alabama. Southern merged with Birmingham College to form Birmingham-Southern College in 1918. The school closed due to financial difficulties in the Spring of 2024.
20. The chapter at Richmond University was originally Alpha Beta. The chapter went inactive in 1881, and its name was reassigned to the University of California, Berkeley in 1886. As a result, the Richmond chapter was called Epsilon Rho when it was reformed in 1958.
21. Chapter formed from Athenaeum, established in 1878.
22. Chapter formed from Omega Sigma Theta, established in 1882.
23. The university and Sigma Chi national both suspended the chapter in October 2019 for serving alcohol while on probation with alcohol restriction. In January 2020, the chapter surrendered its charter.
24. The university suspended the chapter in July 2022.
25. Chapter formed from I.S.C., established in 1882. The chapter was suspended in 1980 following the serious injury of a pledge participating in the chapter's high-risk activities. After the pledge recovered, the chapter was reinstated.
26. The Sigma Chi executive committee revoked the chapter's charter in 1968 after its members had a disagreement with grand counsul Floyd Baker about the fraternity's membership policies. The chapter was reformed in 1972. However, the executive committee suspended the chapter in 1979 for violating the constitution and pledge training policies.
27. Chapter formed from the Crimson Halberd Society, established in 1886.
28. After going inactive, the chapter reformed from Sigma Kappa Delta (local), established in 1912.
29. In January 2021, the university suspended the chapter through the summer of 2024 for violating COVID-19 policies in the fall of 2020.
30. In April 1965, the Sigma Chi executive committee suspended Alpha Omega over rumors that the chapter planned to pledge a Black student, with or without the fraternity's approval. In fact, the chapter offered a bid to a Black student three days before it was suspended. Although the executive committee reinstated it the next year, the chapter decided to disaffiliate on November 10, 1966, because of the fraternity's membership policies. Its charter was revoked by the fraternity on January 21, 1967, and the former chapter's members formed Sigma Chi Omega (local).
31. The Sigma Chi Executive Committee suspended the chapter in 2022 due to accountability issues.
32. Chapter formed from Phi Zeta Mu, established in 1857. The chapter went inactive in 1960 when Dartmouth College banned the discriminatory recruitment policies that were dictated by the fraternity's national constitution, specifically limiting its membership to white males.
33. In October 1964, the chapter surrendered its charter because the fraternity's membership procedure, which gave grand chapter members the ability to veto potential members, conflicted with the university's policy, which required autonomy in membership recruitment at the local level.
34. The chapter disbanded in 1952 over the fraternity's "whites-only" policy.
35. Chapter formed from Delta Rho, established in 1896.
36. Chapter formed from the Egyptians Club, established in 1900. In 2021, the university withdrew its recognition of the chapter for "risk management and member accountability issues". Sigma Chi suspended the chapter and, in February 2022, the chapter surrendered its charter.
37. The chapter formed from Chi Alpha Sigma, established in 1900. The national executive committee suspended the chapter in January 1957 after its membership dwindled.

In June 1963, the chapter had grown and needed more housing than its chapter house could accommodate. It split into Beta Alpha for Western Reserve and Beta Eta for Case. The two chapters consolidated back into Beta Eta when the two colleges merged to form Case Western Reserve University.
44. Chapter formed from Delta Kappa, established in 1902.
45. Chapter formed from Khoda Klan, established in 1907. Later, it absorbed Psi Kappa.

70. Chapter formed from the Delta Club, established in 1927.
71. Chapter formed from Independents Club, established in 1923.
72. The chapter formed from Theta Pi Delta, established in 1923. The Sigma Chi executive committee revoked the chapter's charter in 1963 because the chapter had initiated two Jewish members on April 15, 1962. Changes to the fraternity's constitution had removed the "whites-only" clause but gave any one of the 65 Grand Officers the right to object to a recruit. Although these pledges were not the first Jews to join Sigma Chi, an objection had been raised. The chapter proceeded with the initiation ceremony with the support of its campus advisors, citing the university's policy that prohibited outside involvement in the selection of fraternity members. As punishment, an officer placed the chapter on strict probation for one year, starting on August 29, 1962. However, after debate at the Grand Council meeting in October 1962, this decision was overruled, clearing the way for a new ruling by the executive committee.

83. Chapter formed from Sigma Tau, established in 1919.
