Hrómundartindur (Icelandic pronunciation: [ˈr̥ouːˌmʏntarˌtʰɪntʏr̥] ) is a mountain in Iceland north of Hveragerði with an elevation of 540 metres (1,770 ft). It to the east of Hengill and is the central volcano of an adjacent 25 km (16 mi) long Hrómundartindur volcanic system, which contains the Ölkeduháls geothermal field. Like Hengill this area is close to the south-eastern triple junction of the Hreppar microplate, is seismically active, and associated with the Western volcanic zone and the South Iceland seismic zone. To the north-east are multiple tindars, and there is a Holocene lava flow called Tjarnahnúkshraun which covers 4 km2 (1.5 sq mi) with a volume of 0.03 km3 (0.0072 cu mi). The lava ranges from picrite basalt, being predominantly tholeiite basalt with some basaltic andesite.
