Xiao Qingdao Lighthouse, Maritime lighthouse on Xiao Qingdao Island, China.

Xiao Qingdao Lighthouse is a conical tower 15.5 metres tall, built of white limestone, with two octagonal lower storeys and a cylindrical third storey topped by a riveted steel plate spire. Its total height above sea level is 18 metres, and 30 stone spiral steps lead to the top. It stands on the small island of Xiao Qingdao in Qingdao Bay, at the mouth of Jiaozhou Bay.

German authorities built the lighthouse in 1904 during their control of Qingdao. The structure was part of the maritime infrastructure developed at that time to help ships navigate these coastal waters safely.

In 1936 a city-organized selection of the "Ten Views of Qingdao" listed the island and its lighthouse as "Qin Yu Piao Deng" (Floating Lamp of Qin Island), and the image became one of the city's emblems. The name Qin Dao compares the island's outline to the qin, a Chinese stringed instrument.

The island is now open to visitors and offers views of the Qingdao coastline. The path to the island and tower can be windy, so bringing appropriate clothing is a good idea.

The lighthouse's first light, installed in 1904, was an acetylene lamp flashing red every three seconds, visible four nautical miles away in clear weather. German troops damaged the tower themselves during the 1914 siege of Qingdao; Japanese authorities repaired it the following year and in 1921 fitted a fifth-order dioptric lens giving a red flash every five seconds, visible fifteen nautical miles out.
