I. H. Kempner High School, better known simply as Kempner High School, is a public high school in Sugar Land, Texas and a part of the Fort Bend Independent School District. It was named after Isaac Herbert Kempner (1873–1967), the founder of the Imperial Sugar Corporation, which originally founded Sugar Land as a company-owned town in the early 1900s. Kempner serves areas within Sugar Land, including a portion of First Colony. A small portion of the City of Houston is in the school's boundary.
