Adolph Strecker (21 October 1822 – 7 November 1871) was a German chemist who is remembered primarily for his work with amino acids.

Strecker left Norway on Christian Gottlob Gmelin's death in 1860 to accept the latter's position at the University of Tübingen.

There he conducted research on guanine, xanthine, caffeine, and theobromine, and on the very toxic thallium oxides, which damaged his health severely.

Because of the relative simplicity of the reactants, the Strecker synthesis has been invoked by those studying both the origin of life and meteoritic amino acids.

During one such visit to Darmstadt, Strecker, on July 3, 1852, married Karoline Auguste Natalie Weber (1852–1853), who died 16 months later – on October 13, 1853.
