Dimitri Marick is a fictional character from the American ABC soap opera All My Children. The role has been most notably portrayed by Michael Nader, previously famed for his role on Dynasty. Former head writers Agnes Nixon and Lorraine Broderick created the character in 1991, designing him as a brooding and mysterious character based on heroes from gothic literature, such as Maxim de Winter from Daphne du Maurier's novel Rebecca and Heathcliff from Emily Brontë's novel Wuthering Heights. The character's introduction raised All My Children in the Nielsen ratings and was credited as the "saving grace" of the unpopular Natalie and Janet storyline.

Michael Nader was an American actor, known for his roles as Dex Dexter on the ABC primetime soap opera Dynasty from 1983 to 1989, and Dimitri Marick on the ABC daytime soap opera All My Children from 1991 to 2001, and in 2013. He also starred as Kevin Thompson on the soap opera As the World Turns from 1975 to 1978.
