Andrew "Andy" Sipowicz is a fictional character and protagonist on the popular ABC television series NYPD Blue. Dennis Franz portrayed the character for its entire run.
Sipowicz was a New York City police detective working in the detective squad of the fictitious 15th Precinct of the NYPD, placed on the lower east side of Manhattan. He was the central character of the show during its twelve-year run, and the only one to have been a regular cast member in every episode. (Detective Greg Medavoy (Gordon Clapp) did not appear until episode 3 of the first season and did not become a regular until the start of season 2)
Jason Gay of The Boston Phoenix described Sipowicz as a "drunken, racist goon with a heart of gold" who was "the moral core" of NYPD Blue. In 1997, he described Sipowicz as becoming "sobered up" and that Sipowicz "won't ever go totally soft." Gay describes Dennis Franz as adding "underrated, edgy mixture of grit and sensitivity" to Sipowicz.
