Mark C. Curran is an American law enforcement officer who served as the Sheriff of Lake County, Illinois from 2006 to 2018.

Curran began his career as a state prosecutor in Lake County in 1990, rising to Senior Felony Prosecutor. He then served as a prosecutor with the Illinois Attorney General from 1999 to 2002. In 2002, Curran went into private practice, concentrating in civil and criminal litigation.

In 2006, Curran won the Democratic Party primary election on March 21, 2006, and won the general election in November 2006, defeating incumbent Gary Del Re.[1] Curran has been outspoken in his call for prison reform in Illinois, including faith-based programming in prisons.

In August 2008, Curran made national news when he voluntarily spent a week in the Lake County Jail.[4]

Change of political party[edit]

On December 15, 2008, Curran announced that he was switching from the Democratic to Republican Party, calling his decision a "matter of conscience." Curran stated that the scandals of Democratic Governor Rod Blagojevich played a role in his decision to switch parties
