王筠（1749年 - 1819年），字松坪，号绿窗女史。清代女诗人、戏曲作家。陕西长安县（今属西安市）人。

父王元常，乾隆十三年（1748年）进士，曾官直隶武邑、永清等县知县，工诗，为官亦不废吟咏。王筠自幼颖异，十三四岁即工诗词。适同邑王氏，夫早逝，王筠抚子百龄长大成人，并激励道：「吾于汝家长贫作苦，所望者为进士女复为进士母耳」。嘉庆七年（1802年），百龄亦成进士。

王筠诗词收入《槐庆堂集》，且与父元常、子百龄合刊有《西园瓣香集》。其编写戏曲也颇有造诣，现存传奇《繁华梦》、《全福记》。另有《游仙梦》、《会仙记》等。

Wang Yun (1749–1819) was a Chinese poet and playwright during the Qing Dynasty.

Her birthplace is Chang'an. In her poems she writes about the frustration of educated women, who were not allowed to have a career, nor were they accepted by men as intellectual equals. The Huaiqing Tang ji contains over 200 of her poems. She also wrote three chuanqi plays; Fanhua meng (Dream of Glory), Quan fu ji (Complete Happiness) and You xian meng (A Dream Visit to the Immortals).
