Gerhard Frey (German: [fʀaɪ]; born 1944) is a German mathematician, known for his work in number theory. His Frey curve, a construction of an elliptic curve from a purported solution to the Fermat equation, was central to Wiles' proof of Fermat's Last Theorem.

He studied mathematics and physics at the University of Tübingen, graduating in 1967. He continued his postgraduate studies at Heidelberg University, where he received his Ph.D. in 1970, and his Habilitation in 1973. He was assistant professor at Heidelberg University from 1969–1973, professor at the University of Erlangen (1973–1975) and at the Saarland University (1975–1990) and until 2009, he held a chair for number theory at the Institute for Experimental Mathematics at the University of Duisburg-Essen, campus Essen.

He was a visiting scientist at several universities and research institutions, including Ohio State University, Harvard University, University of California, Berkeley, the Mathematical Sciences Research Institute (MSRI), the Institute for Advanced Studies at the Hebrew University of Jerusalem, and IMPA in Rio de Janeiro.
