Veronica Mars is a 2014 American neo-noir comedy-drama mystery film directed and produced by Rob Thomas, who co-wrote the script with Diane Ruggiero. It is a continuing film adaptation based on the television series of the same name created by Thomas. The film stars Kristen Bell as the title character, alongside an ensemble supporting cast that includes Jason Dohring, Francis Capra, Krysten Ritter, Percy Daggs III, Tina Majorino, Ryan Hansen, Chris Lowell, Max Greenfield and Enrico Colantoni, each reprising their roles. Set nine years after the events of the third season, the plot follows Veronica Mars returning to her hometown in Neptune to investigate the death of a former classmate allegedly murdered by Mars' ex-boyfriend, Logan Echolls.

After the series' cancellation in 2007, Thomas wrote a feature film script, continuing the story. However, Warner Bros. declined to fund the project. On March 13, 2013, Thomas and Bell launched a fundraising campaign on Kickstarter to produce the film. It attained its goal of $2 million in eleven hours, breaking several Kickstarter records, including being the largest successful film project on the website. After raising a budget of $5 million by the end of its run, principal photography began in June 2013 in Los Angeles, and concluded in July 2013. An additional day of shooting took place in December 2013.

Veronica Mars held its world premiere at South by Southwest on March 8, 2014, and was released in the United States in a limited theatrical release and through video on demand on March 14, 2014 by Warner Bros. Pictures. The film received positive reviews from critics and audiences, with many praising the writing and Bell's performance. It earned $3.5 million worldwide against a $6 million budget. The revival of the series has also sparked continuations through different media, including two novels, co-written by Thomas and Jennifer Graham, and a web series centered on Hansen, titled Play It Again, Dick, released on CW Seed. In 2019, Hulu revived the original series for a fourth season.
