Michael Hayes is a TV series that ran on CBS from 1997 to 1998. It stars David Caruso and Ruben Santiago-Hudson.

David Caruso plays in the title role as Michael Hayes. Hayes is an Irish Catholic ex-New York City police officer appointed acting U.S. Attorney for the Southern District of New York State.

This series was Caruso's first attempt at a comeback on television, after he infamously left NYPD Blue a few years earlier and a failed launch into movies, when both Kiss of Death and Jade were box office and critical failures. Despite this, Michael Hayes was cancelled at the end of its first season, and Caruso slowly continued into supporting roles in film and guest spots on television before reaching new heights once again with CSI: Miami, which ran from 2002 until 2012.
