The Kyzyloi Field (Kazakh: Қызылой газ кен орны, Qyzyloı gaz ken orny) is a dry natural gas field in southern Kazakhstan about 65 kilometres (40 mi) to the north of the border with the Karalkalpak region of Uzbekistan and 55 kilometres (34 mi) to the north-west of the Aral Sea.

Kyzyloi Field, which covers 287 square kilometres (111 sq mi), was discovered in 1966.

It contains sweet natural gas (97% methane) in shallow sandstones of Paleogene age at a depth of approximately 600 metres (2,000 ft).

The net proved and probable economically recoverable reserves are approximately 1.42 billion cubic meter.
