Sahotra Sarkar (born 1962) is an Indian-American professor at the University of Texas at Austin, specializing in the philosophy of biology.

He was a visiting scholar at the Max Planck Institute for the History of Science in Berlin (1997–1998, 2002–2003) and taught at Montreal's McGill University before moving to Texas.

[13] In the philosophy of physics Sarkar is known for controversially defending the conventionalism of simultaneity in special relativity (with John Stachel)[14] and suggesting a stochastic modification of quantum dynamics.

Although he denied some of the allegations, he admitted to discussing the possibility of one student posing for nude photographs for money.

[22][23] In November 2019, a group of students interrupted a class Sarkar was teaching in order to protest his continued presence at the university.
