All characters


Played by: Kaley Cuoco in The Big Bang Theory

Penny is the primary female character in the series, befriending her across-the-hall neighbours Leonard Hofstadter (Johnny Galecki) and Sheldon Cooper (Jim Parsons), two physicists who work at the nearby California Institute of Technology (Caltech). Penny's lack of advanced education, but outgoing personality and common sense drastically contrast with the personalities of the primary male characters in the series, even though she is considered part of their group. She is the love interest of Leonard, with whom she maintains a brief romantic relationship during the third season, which is later resumed in the fifth season and culminates in an engagement at the end of the seventh season.
