Costard is a comic figure in the play Love's Labour's Lost by William Shakespeare.

A country bumpkin, he is arrested in the first scene for flouting the king's proclamation that all men of the court avoid the company of women for three years.

By sending love notes to the wrong women and blurting out secrets (including that of an unplanned pregnancy), Costard makes fools of the royal court.

Along with Moth the page and Jaquenetta, a country wench, Costard pokes fun at the upper-class.

Costard makes many clever puns, and is used as a tool by Shakespeare to explain new words such as remuneration.
