Howard Rumsey (November 7, 1917 – July 15, 2015) was an American jazz double-bassist known for his leadership of the Lighthouse All-Stars in the 1950s.

Born in Brawley, California, Rumsey first began playing the piano, followed by the drums and finally the bass. After jobs with Vido Musso and Johnnie Davis, Rumsey became part of Stan Kenton‘s first band. Rumsey soon left Kenton after an argument. He played with Charlie Barnet and Barney Bigard before taking a short hiatus from music. Following this absence from music, Rumsey returned to the Los Angeles jazz scene to form the group the Lighthouse All-Stars. For most of the 1950s this group played each Sunday at the Lighthouse Cafe in Hermosa Beach. During its lifetime, the Lighthouse All-Stars were one of the primary modern jazz institutions on the west coast, providing a home for many Los Angeles musicians. Rumsey died from complications of pneumonia in Newport Beach, California, at the age of 97.
