云吞面，或叫做馄饨面（**当地又称扁食面），是一种在香港的代表面食，中国大陆广州亦十分普遍。以煮熟的馄饨和蛋面，加入热汤即成。

云吞面最早在清末民初，广州西关一带出现，相传是同治年间从湖南传入。据考究，云吞面起初于宋前是用于祭祀的。直到宋代，每逢冬至，各家包馄饨祭祖，祭毕全家长幼分食祭品。富家的一盘祭祀馄饨，有十多种馅，为“百味馄饨”。南宋以后，馄饨传入市肆。初期多数是由小贩肩挑着卖。因为小贩通常在晚间到住宅区出售以应宵夜的习惯，小贩会以小木棒敲打竹板叫卖。后来一些小贩改设店舖经营，甚或加售生滚粥类。经过数十年后，成为今日的云吞面老店。

Wonton noodles (pinyin:Yúntūn miàn; Cantonese Yale:wàhn tān mihn, sometimes called wanton mee ("wanton" is a Cantonese word for dumpling while noodles in Hokkien is "mee" or in Cantonese, "min") is a Cantonese noodle dish which is popular in Guangzhou, Hong Kong, Malaysia, Singapore and Thailand. The dish is usually served in a hot broth, garnished with leafy vegetables, and wonton dumplings. The types of leafy vegetables used are usually kai-lan also known as Chinese kale. Another type of dumpling known as shui jiao is sometimes served in place of wonton. It contains prawns, chicken or pork, spring onions with some chefs adding mushroom and black fungus.
