The Berwin Lee Playwrights Award provides grants to two playwrights, one based in London and one in New York.
Chimerica writer Lucy Kirkwood has won the UK award, whilst on the other side of the Atlantic, the winner is Bathsheba Doran.
This annual award is in its inaugural year and gives each playwright $25,000 without time restrictions for the new project.
Lucy Kirkwood said, “I am delighted and honoured to be the first British beneficiary of the Berwin Lee Theatre Foundation.
"As a commission, it signifies a wonderfully free creative space to work in, for which I am very grateful, and hands stretching across the Atlantic between two great cities of theatre, by which I am very excited.”
