Finding Vivian Maier is a 2013 American documentary film about the photographer Vivian Maier, written, directed, and produced by John Maloof and Charlie Siskel, and executive produced by Jeff Garlin.

Maier was a French-American woman who worked most of her life as a nanny and housekeeper to a multitude of Chicago families. She carried a camera everywhere she went, but Maier's photographic legacy was largely unknown during her lifetime. She died in 2009.

The film documents how Maloof discovered her work and, after her death, uncovered her life through interviews with people who knew her. Maloof had purchased a box of photo negatives at a 2007 Chicago auction, then scanned the images and put them on the Internet. News articles began to come out about Maier and a Kickstarter campaign for the documentary was soon underway.

The film had its world premiere at the 2013 Toronto International Film Festival on 9 September 2013. It was shown in cinemas, and was released on DVD in November 2014. Upon release, the film received critical acclaim, and won various awards, and was nominated for the Academy Award for Best Documentary Feature at the 87th Academy Awards.
