CarMax, Inc. is a used vehicle retailer based in the United States. It operates two business segments: CarMax Sales Operations and CarMax Auto Finance.

In 2021 CarMax, Inc. purchased remaining shares of Edmunds.com, Inc. making it a wholly owned subsidiary. As of January 2025, CarMax operates 253 locations. While CarMax stores focus on marketing used vehicles, the company acquired its first new car franchise with Chrysler Corporation in 1996. By 1999, it added new vehicle franchises for Mitsubishi Motors, Toyota, and Nissan. In late 2021, CarMax sold its last new vehicle dealership, located in Kenosha, Wisconsin, to the Rydell Company.
