The Washington Square Players (WSP) was a theatre troupe and production company that existed from 1915 to 1918 in Manhattan, New York City. It started as a semi-amateur Little Theatre then matured into a Repertory theatre with its own touring company and drama school, while maintaining its goal of presenting only works of artistic merit. It had a great amount of national newspaper coverage and sparked like-minded companies across the country, before it was forced to disband in 1918 due to wartime economic pressure and personnel shortages. Three of its original members would then found the longer-lived Theatre Guild having much the same purpose.
