Ladies' British Open Amateur Stroke Play Championship was founded in 1969 by the Ladies' Golf Union (now merged into The R&A) of Great Britain.

A stroke play tournament over 72 holes, it was discontinued by the R&A after the 2017 tournament won by Linn Grant[1] in favour of a new Girls U16 Amateur Championship.
