Harnetiaux Court is a bungalow court located at 48 N. Catalina Avenue in Pasadena, California. Joseph Harnetiaux and his family built the court in 1922. The court consists of eight single-family homes lining a narrow court and a two-story duplex at the end of the court. The homes were designed in the Colonial Revival style and feature entrance porticos supported by Tuscan columns, jerkinhead roofs, and multi-paned windows. Camphor trees line the front of the court along Catalina Avenue. The court was added to the National Register of Historic Places on November 15, 1994.
