The Ah-ai Grotto (Chinese: 阿艾石窟; pinyin: Ā ài shíkū) is a small, standalone Buddhist rock-cut cave located in the Kyziliya Grand Canyon, Kuqa, Xinjiang.

The grotto was discovered by a young Uyghur shepherd named Tudi Azze (吐地阿孜) in April 1999, while on his way to collecting medicinal herbs.

[2] Built in the 8th century, financially supported by devoted laities, the cave was a product of a flourishing period of Kuchean Buddhism.

A partially survived Amitayurdhyana Sutra Transformation is depicted on the front wall, with its style similar to the Dunhuang murals.

[3] The artistic presentation of Ah-ai Grotto reflects a cultural amalgamation of East Central Asia and Tang dynasty, and the influence of Mahayana Buddhism upon Kucha, which was a Sarvastivada-dominated kingdom.
