Timothy Ludwig Pflueger (September 26, 1892 – November 20, 1946) was an architect, interior designer and architectural lighting designer in the San Francisco Bay Area in the first half of the 20th century. Together with James R. Miller, Pflueger designed some of the leading skyscrapers and movie theaters in San Francisco in the 1920s, and his works featured art by challenging new artists such as Ralph Stackpole and Diego Rivera. Rather than breaking new ground with his designs, Pflueger captured the spirit of the times and refined it, adding a distinct personal flair. His work influenced later architects such as Pietro Belluschi.
