Richard Chai is an American fashion designer. Chai creates clothes for an eponymous label. Before launching his own line, he designed for Marc by Marc Jacobs .

In 2008, he released a capsule line under Target's Go International.

Richard Chai partnered with design firm Snarkitecture for a new pop-up retail store underneath the Highline at 504 West 24th Street, NY. The project entitled "Building Fashion"  and conceived by BOFFO and Spilios Gianakopoulos aimed to promote collaborations between architecture and fashion.

The store carried Chai's men’s and women’s collections and was open for 10 days in October 2010.
