Joseph Helffrich (12 January 1890 in Mannheim, Baden – 1971) was a German astronomer.
He did his Ph.D. dissertation in 1913 at the Landessternwarte Heidelberg-Königstuhl (Königstuhl Observatory, near Heidelberg) at the University of Heidelberg [https://web.archive.org/web/20040623072916/http://www.lsw.uni-heidelberg.de/personnel/diss.phtml].
At the time, the observatory at Heidelberg was a center for asteroid discovery under the direction of Max Wolf, and during his time there Helffrich discovered a number of asteroids.
