Sülüktü, also spelled Sulukta or Suliukta (Kyrgyz: Сүлүктү; Uzbek: Sulukta / Сулукта; Russian: Сулюкта, romanized: Sulyukta) is a town located at the extreme western end of Batken Region in southern Kyrgyzstan. Sülüktü is situated at the southern fringe of the Fergana Valley in a region surrounded on three sides by Tajikistan.

The word "sülüktü" is believed to have come from the Turkic word "suluk" or "zuluk" which means a "leech". According to this view, the waters of present-day Sülüktü had leeches and therefore people called the place "suluktu" which literally means "containing leeches." Sülüktü is one of Central Asia's oldest coal extraction sites. The first industrial coal mine of Sülüktü was opened in 1868. Sülüktü was made into a town in 1940. Sülüktü is the first town in Kyrgyzstan where Soviet rule was established.

Sülüktü is directly subordinated to Batken Region. In other words, it is not part of any district.

In 2021 the population of Sülüktü itself was 14,770 and the combined population of Sülüktü and the subordinated villages was 24,238. Its area is 18 square kilometres (6.9 sq mi).

There were several large coal mines and factories in Sülüktü during Soviet times. Following the collapse of the USSR, the majority of these factories were abandoned. A lack of professionals and machinery, mismanagement, and falling income levels — all contributed to this downfall. While Sülüktü was once an important industrial center, nowadays it gives the impression of an abandoned town.
