Lauren Marcus is an American stage actress. She defined the leading roles of Patty Jenkins, the "frightfully nosey" cheerleader in Joe Iconis' musical, The Plant That Ate Dirty Socks, and Hope Horrishall in Rich Espey's drama Hope's Arbor. From November 2008 through January 2009, she starred as Jenny Vecharelli in the off-Broadway musical Rewrite. She also performed as 'Brooke' in the theatrical production of the musical 'Be More Chill', based on the novel of the same name by the late Ned Vizzini.
Gawker identified Marcus as the character "Janine" on the "Craig and Janine" video series. The video series was subsequently transformed into a live show at the Laurie Beechman Theatre, Craig Stevens Guide to Making it On Broadway, in which Marcus starred alongside Tyler Maynard.
Marcus starred in the Astoria Performing Arts Center's production of Lillian Hellman's The Children's Hour in 2009, playing Mary Tillford. Drama critic David Sheward, writing in Backstage, described Marcus in that role as "a devilish dynamo" and "utterly convincing."
Marcus is a graduate of New Trier High School, New York University and the Royal Conservatoire of Scotland. She currently resides in New York City and is married to musical theater writer Joe Iconis .
