Tilly's (originally known as World of Jeans and Tops) is a United States-based retail clothing company that sells action sports-branded clothing, accessories, shoes, and equipment.

Tilly's stores are located in both traditional outdoor shopping centers and in shopping malls. The average store size is 7,900 square feet (734 m2). Due to their size, Tilly's locations in malls usually take up two or three store spaces. As of May 2013, Tilly's has 182 stores across the US, with about half the stores in California. The company plans to expand to 500 stores in the future.
