The Brazilian Mathematical Olympiad (Portuguese : 'Olimpíada Brasileira de Matemática', also known as OBM) is a mathematics competition held every year for students of Brazil. The participants are awarded gold, silver and bronze medals in accordance with their performance. The main purpose of this competition is to help in selecting students to represent Brazil at the International Mathematical Olympiad.
The Brazilian Mathematical Olympiad has been held since 1979. On that occasion, 11 students were awarded in 1st, 2nd, and 3rd places, and 15 were awarded in the other categories.
In 1991, the competition started to have two levels: Junior, for students with a maximum of 15 years; and Senior, for high school students. Over the years, there have been changes, such as the creation, in 2001, of the University level, with two phases.
In 2017, OBM was integrated into OBMEP. It is then carried out in a single phase, for levels 1, 2, and 3, only for invited students, considering, among other criteria, the score obtained in the second phase of the OBMEP. The University level is maintained, in two phases, but it counts on the individual registration of the undergraduate student.
In 2019, the Brazilian Mathematical Olympic Association (AOBM) began hosting Torneio Meninas na Matemática (Girls in Mathematics Tournament), also known as TM². The event is also annual, however exclusive to female students from 8th grade onwards. The awarded students in this competition get to participate in the following year's OBM.
Since 2020, another competition organized by AOBM, Competição Elon Lages Lima de Matemática (named after Brazilian mathematician Elon Lages Lima), serves as the official first phase of OBM for university students, with the second phase now being labeled "Fase Única" (Single Phase). Moreover, since 2022, students in Middle and High School can also subscribe themselves to participate in Competição Jacob Palis Jr. de Matemática (named after Brazilian mathematician Jacob Palis), in which the awarded students can take part in the OBM edition of the same year (female students who are awarded also compete in the following edition of TM²).
The exams are subdivided into four levels, according to the student's education level.
The Instituto Nacional de Matemática Pura e Aplicada is considered to be the foremost research and educational institution of Brazil in the area of mathematics. It is located in the city of Rio de Janeiro, and was formerly known simply as Instituto de Matemática Pura e Aplicada (IMPA), whose abbreviation remains in use.

Maurício Matos Peixoto,, was a Brazilian engineer and mathematician. He pioneered the studies on structural stability, and was the author of Peixoto's theorem.
Elon Lages Lima was a Brazilian mathematician whose research concerned differential topology, algebraic topology, and differential geometry. Lima was an influential figure in the development of mathematics in Brazil.
Artur Avila Cordeiro de Melo is a Brazilian mathematician working primarily in the fields of dynamical systems and spectral theory. He is one of the winners of the 2014 Fields Medal, being the first Latin American and lusophone to win such award. He has been a researcher at both the IMPA and the CNRS.

The Brazilian Physical Society is a non-profit organization of physicists and physics teachers, affiliated with the Brazilian Society for the Progress of Science . Its main missions are to promote the advancement and dissemination of knowledge in physics and science; to defend academic freedom, as well as the interests and rights of professionals in physics, and to contribute to initiatives and public policies aiming to improve the training and harnessing of physics teachers and physicists to help the scientific and technological development of Brazil.
Welington Celso de Melo was a Brazilian mathematician. Known for his contributions to dynamical systems theory, he served as full professor at Instituto Nacional de Matemática Pura e Aplicada from 1980 to 2016. Melo wrote numerous papers, one being a complete description of the topological behavior of 1-dimensional real dynamical systems . He proved the global hyperbolicity of renormalization for Cr unimodal maps. He was a recipient of the 2003 TWAS Prize.
The Brazilian Mathematical Society is a professional association founded in 1969 at Instituto de Matemática Pura e Aplicada to promote mathematics education in Brazil.
The Brazilian Mathematical Olympiad of Public Schools (OBMEP) is an annual Mathematics contest created in 2005 by the Brazilian Ministério da Ciência e Tecnologia (MCT) and Ministério da Educação (MEC), in collaboration with Instituto Nacional de Matemática Pura e Aplicada (IMPA) and Sociedade Brasileira de Matemática (SBM), to stimulate the mathematics education in Brazil. It is open to public school students from fifth grade to high school. In 2014 more than 18 million students were enrolled for its first round.
Fernando Codá dos Santos Cavalcanti Marques is a Brazilian mathematician working mainly in geometry, topology, partial differential equations and Morse theory. He is a professor at Princeton University. In 2012, together with André Neves, he proved the Willmore conjecture. Since then, among proving other important conjectures, Marques and Neves greatly extended Almgren–Pitts min-max theory to prove theorems about minimal surfaces.
Marcelo Miranda Viana da Silva is a Brazilian mathematician working in dynamical systems theory. He proved the Zorich–Kontsevich conjecture together with Artur Avila.
Carlos Gustavo Tamm de Araújo Moreira is a Brazilian mathematician working on dynamical systems, ergodic theory, number theory and combinatorics. Moreira is currently a researcher at the Instituto Nacional de Matemática Pura e Aplicada (IMPA), where he goes by the nickname "Gugu". He is also a member of the Brazilian Mathematical Olympiad Commission, a fanatic fan of the Brazilian football team Flamengo and a member of the Brazilian Communist Party (PCB). In October 2016, he achieved the mark of 5000 goals scored in his amateur football career. He maintains a record of his goals to show to the incredulous.
The Olimpíada de Matemática do Grande ABC, or OMABC is a mathematical competition for pre-collegiate Brazilian students of Grande ABC region, composed by the following cities:
