Vanessa Rosalia Marquez (December 21, 1968 – August 30, 2018) was an American actress. She was primarily known for her recurring role in the first three seasons of ER as nurse Wendy Goldman, as well as her role as Ana Delgado in the 1988 biographical drama film, Stand and Deliver.

Prior to her death, Marquez made headlines related to the #MeToo movement, alleging that she endured harassment while on the set of ER. In October 2017, she accused series star George Clooney of helping to "blacklist" her after she complained to executives about the harassment. Clooney denied the allegations.
