The actor is suing Capri Anderson, who was found locked in the bathroom of his Manhattan hotel suite last month. He filed suit hours after Anderson went on ABC's "Good Morning America" and accused him of using racial slurs and grabbing her by the throat.
Sheen's lawsuit claims Anderson threatened to make false allegations about the star unless he paid her $1 million.
The suit says Anderson's allegations are false and calls them a "sensational tale."
Sheen's filing pre-empts a lawsuit Anderson said she would file against Sheen for battery and false imprisonment.
A phone message for Anderson's attorney, Keith Davidson, wasn't immediately returned.
ABC is owned by the Walt Disney Co.
