Abigail Kathleen Breslin (born April 14 1996) is an Academy Award-nominated American actress. The fourth youngest actress ever to be nominated for a competitive Academy Award, Breslin is known for her role in the film Little Miss Sunshine, as well as for several supporting parts in other Hollywood films.

It's not surprising that Abigail Breslin, the tiny, serious, slightly eccentric Bo in M. Night Shyamalan's Signs (2002), comes from an acting family - her older brother is child-actor Spencer Breslin. It's clear from her amazingly strong and true performance in that movie that she is no stranger to the movie-making process. A native New Yorker born in that city in 1996, Breslin has been in front of the camera since the age of three, making commercials until eventually cast by Shyamalan to play Mel Gibson (I)'s daughter in Signs (2002). Breslin's performance in Signs (2002) garnered her great praise and earned her work on television as well as additional movie roles, including in Raising Helen (2004), in which Breslin had the treat of acting alongside her real-life brother Spencer, and became friends with star Kate Hudson (I). As she matured, she became a much sought after actor, and has gone on to win numerous awards for her performances, not to mention an Oscar nomination for her work in Little Miss Sunshine (2006). Even from an early age, Breslin has brought a great deal of intensity to her performances, and is known in the industry for her professional attitude.
