Chasing Madoff is a 2010 documentary film written and directed by Jeff Prosserman.

It was first released at the International Documentary Film Festival in Amsterdam on 19 November 2010.

The film chronicles how Harry Markopolos and his associates spent ten years trying to get the U.S. Securities and Exchange Commission (SEC) and others to acknowledge and act on their investigative proof of Bernie Madoff's Ponzi scheme, which scammed an estimated $18 billion, or $65 billion including fake returns, from investors.

Despite a series of meetings over a number of years, the SEC ignored Markopolos and his associates or only gave the evidence a cursory investigation.

The website's consensus reads: "Chasing Madoff admirably highlights Harry Markopolos' perilous crusade against one of history's biggest frauds, but the documentary's disinterest in Madoff himself makes it feel like only half the story.
