Gauldal or Gauldalen (English: Gaula River valley) is a valley and traditional district in Sør-Trøndelag county, Norway. The Gaula River runs through the valley before flowing into the Trondheimsfjord.
The district includes the municipalities of Holtålen, Midtre Gauldal, and Melhus. The municipality of Røros is often (traditionally) counted as a part of the district, even though it lies outside the actual Gaula River valley.[1]
