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.
