The Meteora is a rock formation in the regional unit of Trikala, in Thessaly, in northwestern Greece, hosting one of the most prominent complexes of Eastern Orthodox monasteries, viewed as second in importance only to Mount Athos. Their height is more than 20 metres (66 ft).

Twenty-four monasteries were established atop the giant natural pillars and hill-like rounded boulders that dominate the local area, mainly from the second half of the 14th century. As of December 2025, four of the original monasteries were occupied, in active use as monasteries that are managed by monks, and open to visitors: the monasteries of Great Meteoron (est. 1356), Varlaam, Holy Trinity, and Saint Stephen – the latter became a convent run by a community of nuns in 1961.

The Meteora complex, comprising the six extant monasteries, was added to the UNESCO World Heritage List in 1988 because of its outstanding architecture and beauty, combined with religious and cultural significance.

The name means "lofty", "elevated", and is etymologically related to meteor.
