Oymyakon is a rural locality (a selo) in Oymyakonsky District of the Sakha Republic, Russia, located in the Yana-Oymyakon Highlands, along the Indigirka River, 30 km northwest of Tomtor on the Kolyma Highway.
It is named after the Oymyakon River, whose name reportedly comes from the Even word kheium, meaning "unfrozen patch of water; place where fish spend the winter". However, another source states that the Even word heyum (hэjум; kheium may be a misspelling), which means "frozen lake", may be where it gets its name.
Oymyakon has two main valleys beside it. These valleys trap wind inside the town and create a colder climate. The temperatures here are extremely cold for most of the year, and it snows frequently in spring and autumn, but rarely in summer and winter, due to the Siberian High in winter and temperatures are commonly above 0 °C in summer. Schools are closed if it is colder than −55 °C.
Local economy is mostly fur trading and ice fishing. Over the last few decades, the population of Oymyakon has shrunk significantly. The village had a peak population of roughly 2,500 inhabitants, but that number has dwindled to fewer than 900 in 2018.
