Aktogay (Kazakh: Ақтоғай, Aqtoğai, اقتوعاي Kazakh pronunciation: [ɑqtwʊʁɑj]) is a town in Ayagoz District, Abai Region of Kazakhstan and major railway hub of Turkestan-Siberian Railway.

The capital cost account $1.5-2 billion and the production capacity is 100.000 tones per annum.

As a result of the Soviet–Chinese accords of 1956, the railway to Dostyk (in Alataw Pass) was built in 1959, but by that time relations between two countries had soured and Chinese Lanxin railway was not extended to Kazakhstan border in the following thirty years.

In 1985 Aktogay was linked with Sayaq station, so a railway connection to Central Kazakhstan become available.

In 2012, a new line was opened between Zhetigen, via a break-of-gauge trans-shipment hub at Korgas, to a junction in China at Jinghe.
