La Lumiere School, in La Porte, Indiana, United States, is a private, college preparatory boarding and day school founded in 1963.

La Lumiere School is an educational institution, begun in 1963, as a single-sex boarding and day school for boys. In 1978, girls of comparable age were admitted to the school. The present day school serves an internationally and culturally diverse, co-educational body of 75 boarders and a population of nearly 125 local day students. Recent facilities expansion has allowed a gradual growth of school population to its largest size since the founding of the school.

La Lumiere's Science Olympiad team has competed at the state level for the past eighteen years. School traditions include the senior run at the bonfire, an all-school speech contest, formal holiday dinners for faculty and students, two major drama productions, and the headmaster's swim after major gridiron victories. Athletic teams do not compete in a conference structure; the school maintains its independent status and competes regionally against a variety of other independent, parochial, and public schools.
