Moishe Rosen (born 12 April 1932) is the founder and former President of Jews for Jesus, an evangelical missionary organization working to persuade Jewish people that Yeshua (the Hebrew/Aramaic name preferred for Jesus by the Messianic movement) is the promised Messiah.

Rosen was raised in Denver, Colorado, in an Orthodox Jewish family. He married Ceil Starr on 18 August 1950; both were converted to Christianity in 1953. Rosen subsequently worked as a missionary among Jewish people from 1956 onwards, and was ordained as a Baptist minister in 1957. He continued his missionary activities, which culminated in his decision to found Jews for Jesus in 1973. He retired from his position as Executive Director in 1996, but remains one of fifteen board members.

Rosen is known as a flamboyant figure with a strong personality. He openly calls himself both a "Christian" and a "Messianic Jew" - two labels that many others studiously avoid using together. Within the Messianic movement, which comprises a spectrum of beliefs ranging from evangelical Christianity with a Jewish flavour at one end, to beliefs and practices seeking to emulate Orthodox Judaism with Yeshua added at the other, Rosen is firmly at the "evangelical pole" of the spectrum. Despite some controversy, he has remained in the evangelical mainstream.

In 1997, the Conservative Baptist Association named him a "Hero of the Faith."

Rosen has authored numerous books. These include:

• Sayings of Chairman Moishe (1972)
• Jews for Jesus (1974)
• Share the New Life with a Jew (1976)
• Christ in the Passover (1977)
• Yeshua: the Jewish way to say Jesus (1982)
• Overture to Armageddon (1991)
• The Universe is Broken: Who on Earth Can Fix It? (1991)
• Demystifying Personal Evangelism (1992)
• Witnessing to Jews (1998)
