Jed Allan has starred in several soap operas. He made his debut as trouble-making Ace Hubbard on Love of Life in 1964. From 1964-65, he was one of many actors to play college professor Paul Britton on The Secret Storm who was involved with the show's leading heroine, Amy Ames. Allan replaced his future Santa Barbara co-star Nicolas Coster in the part. He may be best known for his role as Don Craig in Days of Our Lives, which he played from 1971 to 1985, his exit taking place as many of the show's veteran cast members were being written out so the show could focus on younger characters. His departure from Days of our Lives was controversial, as his character was abruptly written out with no further explanation. He gained a new audience when he took over the role of C.C. Capwell in Santa Barbara from 1986 to 1993. After his time on Santa Barbara, Allan had a recurring role in Beverly Hills, 90210 playing Rush Sanders.
In 2004, he started playing the role of Edward Quartermaine in General Hospital. This was in some ways unusual casting, as the actor who played Edward's son Alan, Stuart Damon, is a month older than Allan himself. Prior to starring on General Hospital he starred in its spinoff Port Charles. In 2006, it was announced that John Ingle, the actor who had played Edward before Allan, was returning, and Allan would relinquish the role. Ingle returned to the role in spring 2006.[
