The Samuel Curtis Johnson Graduate School of Management is the graduate business school in the SC Johnson College of Business at Cornell University, a private Ivy League university located in Ithaca, New York. It was founded in 1946 and renamed in 1984 after Samuel Curtis Johnson, founder of S.C. Johnson & Son, following his family's $20 million endowment gift to the school in his honor—at the time, the largest gift to any business school in the world.

The school is housed in Sage Hall and supports 58 full-time faculty members. There are about 600 Master of Business Administration (MBA) students in the full-time two-year (2Y) and Accelerated MBA (1Y) programs and 375 Executive MBA students. The school counts over 15,200 alumni and publishes the academic journal Administrative Science Quarterly.
