Steinkjerⓘ (Norwegian) or Stïentje (Southern Sami)[4] is the administrative centre of Steinkjer Municipality and Trøndelag county in Norway.

The town[1] is located at the northeastern end of the inner-most part of the Trondheimsfjorden, at the mouth of the river Steinkjerelva.

The town is split in two by the river Steinkjerelva, creating the two traditional neighborhoods of Nordsia and Sørsia.

Both the European route E6 highway and the Nordlandsbanen railway line run through the town, the latter serving the city at Steinkjer Station.

On 1 January 1964, a large merger took place which merged the following places to form a new, larger Steinkjer Municipality:[6] The town (and municipality) is named after the old Steinkjer farm (Old Norse: Steinker) since the town was built on the site of the old farm.
