The Shield is an American crime drama television series starring Michael Chiklis that premiered on March 12, 2002, on FX in the United States, and concluded on November 25, 2008, after seven seasons. Known for its portrayal of corrupt police officers, it was originally advertised as Rampart in reference to the true-life Rampart Division police scandal, on which the show's Strike Team was loosely based. The series was created by Shawn Ryan and The Barn Productions for Fox Television Studios and Sony Pictures Television.

Several notable actors took extended roles on the show, including Glenn Close, who was the female lead during the fourth season; Michael Peña, in season 4; Anthony Anderson, in seasons 4, 5, and 6; Forest Whitaker, who guest-starred in seasons 5 and 6; Laura Harring, in season 5; Franka Potente, in season 6; and Laurie Holden, in season 7.

The series has received critical acclaim and is widely regarded as one of the greatest television series of all time.
