The Lucille Lortel Award for Outstanding Featured Actress in a Musical was an award presented annually at the Lucille Lortel Awards to honor an actress for excellence in a featured role in an Off-Broadway musical production. This category was added in 2014, as the awards were split into Outstanding Featured Actress in a Play and Outstanding Featured Actor in a Musical, before being retired in favor of gender-neutral categories in 2021.
Luba Mason and Leslie Rodriguez Kritzer are the only performers nominated multiple times in this category, with two nominations each (and Kritzer winning once).
Several musical performers won or received nominations for the Lucille Lortel Award for Outstanding Featured Actress before it was split in 2014. Musical winners in the former category include:
