Friedrich Tietjen (1832, Westerstede, Oldenburg – 1895) was a German astronomer.[2]

He was director of the Astronomisches Rechen-Institut (ARI) from 1874 until his death in 1895. The Minor Planet Center credits him with the discovery of one minor planet, the 120-kilometer sized asteroid 86 Semele.[1]

The main-belt asteroid 2158 Tietjen, discovered by Karl Reinmuth at Heidelberg Observatory in 1933, was named in his memory.[2]
