Dick Lammi (January 15, 1909 – November 29, 1969) was an American jazz tubist and bassist associated with Dixieland jazz.
Lammi played violin and banjo early in his career, and played as a banjoist in various groups in the Pacific Northwest in the late 1920s. He settled in Portland, Oregon in the early 1930s, and played bass in a group there; after a move to San Francisco in 1936, he began playing tuba alongside bass. His best-known work was as a member of Lu Watters's band, the Yerba Buena Jazz Band. Lammi played in the ensemble from 1941 to 1950, including on virtually all of their recordings.
