Youtiao (traditional Chinese: 油條; simplified Chinese: 油条; pinyin: Yóutiáo), known in Southern China as yu char kway, is a long golden-brown deep-fried strip of wheat flour dough of Chinese origin and (by a variety of other names) also popular in other East and Southeast Asian cuisines.

Conventionally, youtiao are lightly salted and easily separated by hand. Youtiao are normally eaten at breakfast as an accompaniment for rice congee, soy milk or cow's milk blended with sugar. Youtiao may also be known as a Chinese cruller, Chinese oil stick, Chinese donut [sticks], and fried breadstick, among others.

In other Asian countries, they may also be called bicho, you char kway, cakwe, cakoi, kueh, kuay, shakoy or pathongko, among other names.

At breakfast, youtiao can be stuffed inside shāobǐng (traditional Chinese: 燒餅; simplified Chinese: 烧饼; lit. 'roasted flatbread') to make a sandwich known as shāobǐng yóutiáo (traditional Chinese: 燒餅油條; simplified Chinese: 烧饼油条). Youtiao wrapped in a rice noodle roll is known as zháliǎng. In Yunnan, a roasted rice flour pancake usually wrapped around a youtiao is known as erkuai (traditional Chinese: 燒餌塊; simplified Chinese: 烧饵块). Yet another name for a sandwich variant is jianbingguǒzi (traditional Chinese: 煎餅果子; simplified Chinese: 煎饼果子; lit. 'youtiao and fried bread').

Youtiao is occasionally dipped into various liquids, for example the soup xidoufen, soy milk (sweet or salty), and soy sauce.

Youtiao is also an important ingredient of the food cífàn tuán in Shanghai cuisine.

Tánggāo (Chinese: 糖糕), or "sugar cake", is a sweet, fried food item similar in appearance to youtiao but shorter in length.

In Thailand, youtiao or pathongko (ปาท่องโก๋) in Thai are eaten for breakfast with soy milk or porridge.
