Hans Friedrich August Carste (5 September 1909 in Frankenthal – 11 May 1971 in Bad Wiessee) was a German composer and conductor.
In 1937, when Ludwig Rüth, the Jewish band leader, emigrated to South Africa, Hans Carste took up the baton.
For some time the orchestra was still known as the Ludwig (Lewis) Rüth Orchester but acknowledged that Carste was the conductor.
Released in 1948, he returned to Germany, becoming one of the musical directors at Rundfunk im amerikanischen Sektor (RIAS) radio station in Berlin, and once again working for the stage and movies.
He also composed the music for the song "Du spielst 'ne tolle Rolle", which was recorded by the Andrews Sisters and Nat King Cole, with English lyrics by Charles Tobias, as "Those Lazy-Hazy-Crazy Days of Summer".
