Hamar Cathedral (Hamar domkirke) is the seat of the Diocese of Hamar, part of the Lutheran Church of Norway.
The church was erected as a result of Hamar achieving city status in 1849 and re-emerged as an independent diocese two years later. Noting rapid growth and the need for a diocese to cover areas of eastern Norway, the Church of Norway established the seat for the newly formed diocese of Norway in Hamar in 1864. The architect for the cathedral was Heinrich Ernst Schirmer, the local general contractor was Herman Frang. The cathedral was consecrated for services on 15 December 1866. The exterior was built in simple, nearly austere German Romanesque style and is largely unchanged since its construction.
In the 1920s, several changes were made to the interior. In 1950, bishop Kristian Schjelderup called for a significant renovation of the interior. Arnstein Arneberg was commissioned as architect, and his design called for nearly completely gutting the interior. All that remain from the original interior are the supporting structure for the organ loft, only the baptismal font and two silver candlestick holders. The new interior was opened on May 9, 1954.
