Claire L. Evans is an American singer, writer, and artist based in Los Angeles, California. She is the lead singer of the pop duo YACHT.

Evans joined YACHT in 2008 after sharing a "mystical experience" with collaborator Jona Bechtolt, and has recorded three albums, See Mystery Lights, Shangri-La, and I Thought the Future Would Be Cooler with Bechtolt. She also appeared as a guest on YACHT's third album, I Believe in You. Your Magic Is Real. Known for her androgynous onstage persona as a performer, she has been called a "neo-Annie Lennox" by the New York Times. NPR music journalist Bob Boilen has referred to her as "one of the most striking performers I've seen in a rock band."

In addition, Evans is a journalist and author of Broad Band: The Untold Story of the Women Who Made the Internet. With a popular science and culture blog, Universe, hosted by National Geographic's Scienceblogs network, her essay for Universe, "Moon Art: Fallen Astronaut" was anthologized in The Best Science Writing Online 2012.
