Russell Athletic is an American clothing manufacturer based in Bowling Green, Kentucky. Currently a subsidiary of global company Fruit of the Loom, Russell Athletic was the main brand of Russell Brands, LLC. until its acquisition in 2006.

Founded in 1902, the company produced team uniforms for a wide range of sports, such as American football, basketball, baseball, softball, and volleyball. Russell Athletic supplied jersey uniforms and apparel for many professional sports teams of the major professional sports leagues in the United States and Canada, and also high schools, colleges, universities, and minor league teams, until it shut down its team uniform division in 2017. Nevertheless, manufacturing of team uniforms restarted in 2018 through an agreement with Georgia-based company Augusta Sportswear.

Today, Russell Athletic primarily focuses on casual wear, producing t-shirts, hoodies, jackets, sweatpants, shorts and underwear. The company also manufactures American football, baseball/softball, and basketball uniforms in its partnership with Augusta Sportswear.
