Tistedalen is a part of Halden in Østfold, Norway. Originally located four kilometers from the city center, the area started growing up around the sawmill industry and has now been engulfed by Halden, although it still maintains some separate identity. Traditionally, Norway's largest sawmill industry was located in Tistedalen. In the 20th century, Tistedalen became a classic working class community, surrounded by small factories. There is some presence of different religious groups.
