A four-month stint as the mysterious Charlotte Greer on Ryan's Hope in 1983 brought Chapman critical acclaim. Her role had her character as part of a revenge plot against the Ryan family after lying to the press that she was Frank Ryan's ex-wife. She joined the cast of General Hospital the following year as the devious Ginny Blake who was the biological mother of Mike Webber, adopted by Rick and Lesley. After Lesley's "death", Rick and Ginny married in an attempt to share custody and fell in love after Ginny was found to be the killer of D.L. Brock. She received Soap Opera Digest Award for Outstanding Lead Actress in a Daytime Drama nomination for her performance. After that stint ended, she had a brief role on One Life to Live as Sandra Montaigne, a con-artist out to scam ex-boyfriend Jonathan Russell. She was the third former General Hospital actress to play the role of Anjelica Devereaux Curtis on Days of Our Lives, playing that part from 1989 to 1990 and briefly in 1991.
Chapman made her first appearance on The Young and the Restless after that, briefly subbing for Jess Walton as Jill Abbott. She joined the cast of The Young and the Restless full-time in January 2005, replacing Joan Van Ark in the contract role of Gloria Fisher.[6] In March 2011, it was announced that Chapman had been taken off her contract and bumped to recurring.[7] In October 2014, it was announced that she would make a guest appearance as Gloria on The Bold and the Beautiful. She appeared in a few more episodes of The Young and the Restless in 2015 and 2016. She played Diana Cooper on Days of Our Lives for two months in 2019, then returned to Y&R.[8][9]
