The cast dressed up for a formal dinner party during season 6.

The following is a list of episodes of the CBS sitcom The Big Bang Theory.

Like the name of the series itself, with the exception of the first episode – "Pilot" – episode titles of The Big Bang Theory always start with "The", and resemble the name of a scientific principle, theory or experiment, whimsically referencing a plot point, script line or quirk in the episode. The writers have used 109 different scientific principles in the episode titles as of November 2014 with "hypothesis" used the most (five times) followed by "excitation", "insufficiency", "reaction", "turbulence" and "vortex", four times each.

As of November 27, 2014, 170 episodes have been aired.
