Dandan Oilik is a deserted historical town and desert oasis in the Taklamakan Desert of Xinjiang, China. Dandan Oilik was an important (though small) centre of local Buddhism and trade on the Silk Road. Its name means 'Houses of Ivory' and has been the site of a small number of significant archeological finds.

Having been abandoned hundreds of years ago, the oasis was found and lost to shifting desert sands several times. Most recently, a German expedition led by Christoph Baumer found the city based on the accounts of previous explorers such as Sir Aurel Stein, and uncovered relics dating to the 7th and 8th Century. They also marked its GPS position, and the city is now being studied by Chinese archeologists.
