Heddal Stave Church is a parish church of the Church of Norway in Notodden Municipality in Telemark county, Norway. It is located in the village of Heddal. The wooden, triple nave stave church was built in a long church design around the year 1200 using plans drawn up by an unknown architect.

The church is one of the 28 surviving stave churches in Norway and it is considered to be the largest of the stave churches. It was constructed entirely out of wood at the beginning of the 13th century, and it was dedicated to the Virgin Mary. After the Reformation, the church was in very poor condition. A major restoration of the building took place during 1849–1851. However, because the restorers lacked the necessary knowledge and skills, another restoration was required in the 1950s. The interior was marked by the period after the Reformation in 1536–1537 and is for a great part a result of the restoration that took place in the 1950s.
