The Lukeino Formation is a geologic formation located in Kenya and it dates to the Late Miocene (Messinian).[1]

The Lukeino Formation is believed to have been formed through continued tectonic plate activity, and it was located within a well-forested region[3] that was located nearby to Paleolake Lukeino.[2]
