Oscar is an unincorporated community located in the southeastern portion of Pointe Coupee Parish, Louisiana, United States.

[2] Oscar's most noted resident was the novelist Ernest J. Gaines, who was the fifth generation of his family to be born on the River Lake plantation, where his ancestors had been enslaved and then sharecroppers.

Gaines left Oscar for California at age 15, and went on to a storied career as a novelist, winning the National Book Critics Circle Award for fiction, the National Humanities Medal, and a MacArthur "genius grant".

[4][5] A few months later, the American Missionary Association sent another teacher, Alfred Lawless, to Oscar to reopen the school.

His son, who was living with his father in Oscar at the time, became the noted doctor and philanthropist Theodore K. Lawless.
