Prohibit Abortion and Gender Transition Procedures for Minors Amendment

Missouri Amendment 3 is a legislatively referred constitutional amendment that will appear on the ballot in the U.S. state of Missouri on November 3, 2026. [1] If passed, the amendment would ban abortion in the state, except in cases to protect the life of the mother, or, up to 12 weeks, in cases of rape and incest. [2] It would also prohibit medical professionals from administering gender-affirming medical care to minors, which is already banned until August 2027 in the state via Senate Bill 49. [3]

A lawsuit was filed in July 2025 by the ACLU of Missouri challenging the ballot language for Amendment 3. [4] In September 2025, a Cole County judge ordered the Secretary of State to modify the amendment's ballot language, to clarify that it would repeal Amendment 3, an amendment passed in November 2024 protecting access to reproductive care in the state. [5]

The following question and information will be shown to voters: [6]

Shall the Missouri Constitution be amended to:

State governmental entities estimate no costs or savings. Greene County estimates it may experience an unknown increase in tax revenue. Other local governmental entities estimate no costs or savings.

Fair Ballot Language:

A “yes” vote will repeal Article I, Section 36, of the Missouri Constitution approved by the voters in 2024 which provided reproductive healthcare rights, including abortion through fetal viability; continue to ensure women’s ability to access medical care for medical emergencies, ectopic pregnancies, and miscarriages; allow legislation to regulate abortion providers and facilities to ensure health and safety; require informed and voluntary consent for an abortion, including parental or judicial consent for minors; allow restriction of abortions to cases of medical emergency, rape and incest under twelve weeks gestation, and fetal anomalies; prohibit public funding of abortions except in limited circumstances; and prohibit gender transition procedures for minors including gender transition surgeries, cross-sex hormones or puberty-blocking drugs, with exceptions for specific medical conditions.

A “no” vote will leave Article I, Section 36, of the Missouri Constitution approved by voters in 2024 in place; will not limit abortion to cases of medical emergency, rape and incest under twelve weeks gestation, and fetal anomalies, but leave access to abortion available through fetal viability; will not prohibit gender transition procedures for minors.

If passed, this measure will not increase or decrease taxes.
