Benjamin Constant Botelho de Magalhães (Niterói, 18 October 1836 – Rio de Janeiro, 22 January 1891) was a Brazilian military man and political thinker.

Primarily a positivist, influenced heavily by Auguste Comte, he was the founder of the positivist movement in Brazil (Sociedade Positivista do Brasil, Brazilian Positivist Society), and later this led to his republican views. He left the Brazilian Positivist society because of internal disagreements, but remained an ardent pupil of Comte until the end of his life.

Benjamin Constant had a difficult childhood and attempted suicide at the age of 12. He served in the Paraguayan War, and had a large family. He felt underpaid and unhappy as a soldier. An intellectual at heart, he was a great supporter of Comte's Religion of Humanity.

His Republican views led him to found the Clube Militar (or Military Club), with Deodoro da Fonseca, in May 1887. It was based in the Praia Vermelha Military School, and, shortly before his death, overthrew the emperor and helped establish a republic.

The Brazilian town of Benjamin Constant, near the Amazon river and the Peruvian border, was named after him.

He was considered the founder of the Republic in the Constitution of 1891.
