Haltdalen Stave Church (Norwegian: Haltdalen stavkyrkje) is a stave church built in the 1170s originally from the village of Haltdalen in what is now the municipality of Holtålen in Trøndelag county, Norway. The church is now on display at the Sverresborg Trøndelag Folkemuseum in the city of Trondheim.
The church originated in Haltdalen, where it served as the parish church. It was probably built in the 1170s. The church was moved to Trondheim during the 1880s. Church was re-located to the Sverresborg Trøndelag Folkemuseum in 1937. The church has been disassembled several times, which has led to repeated repairs. Significant original parts have been preserved for 800 years.
The church on display today is a re-built version of two separate churches from neighboring locations: Haltdalen and Ålen. The western wall and the portal are from the old Ålen stave church. This is a single-nave stave church of the east Scandinavian-style, and it is the only one that is preserved. 
In commemoration of the thousandth anniversary of the conversion of Iceland to Christianity, developing a suggestion by the Icelandic government, the Norwegian state presented Iceland with a replica of the Haltdalen church, which was erected by the harbour of Vestmannaeyjabær in the Vestmannaeyjar, in an area formed by the lava of the 1973 eruption of Eldfell. The replica was undertaken by the Norwegian Institute for Cultural Heritage Research as a three-year research and reconstruction project from 1998 to 2000 under the leadership of Elisabeth Seip. The church was constructed at Lom from materials deliberately drawn widely from around Norway, including timber from Røros, shingles from Odalen, tar from Skjåk, wrought iron from Vågå, and a doorstep from Holtålen. A gallery was added around the outside of the building, inspired by other stave churches, to provide the building with extra strength against the stormy weather of the Vestmannaeyjar. The church was built and consecrated in summer 2000. The project was supported by a Norwegian government grant of 5.5m Norwegian kroner; Icelandic government funding for the redevelopment of the Skansinn area of Vestmannaeyjarbær as a heritage area; and some private sponsorship was also involved, most importantly that the Icelandic company Eimskip shipped the church to Iceland for free.
