Øysletta[2] is a village in Overhalla Municipality in Trøndelag county, Norway.

It is located on the south shore of the river Namsen, along the now-defunct Namsos Line railway.

The municipal center, Ranemsletta lies about 7.5 kilometres (4.7 mi) to the northwest and the municipal border with Grong Municipality lies about 3 kilometres (1.9 mi) east of Øysletta.

A geo-radar survey revealed in 2019 the presence of a group of Viking ship burials, the most significant of which appears to be over 8 metres (26 ft) long.

Due to the COVID-19 pandemic, excavations were delayed until 2023, and will last for years.
