Lom is a municipality in Innlandet county, Norway. It is located in the traditional district of Gudbrandsdal. The administrative centre of the municipality is the village of Fossbergom. Another village area in Lom is Elvesæter.

The 1,969-square-kilometre (760 sq mi) municipality is the 38th largest by area out of the 356 municipalities in Norway. Lom is the 266th most populous municipality in Norway with a population of 2,212. The municipality's population density is 1.2 inhabitants per square kilometre (3.1/sq mi) and its population has decreased by 6.4% over the previous 10-year period.

Lom is famous for its extensive history, for Lom Stave Church, one of the few remaining stave churches in Norway. Also for being located in the midst of the highest mountains in Northern Europe.

The prestegjeld (parish) of Lom was established as a municipality on 1 January 1838 (see formannskapsdistrikt law). On 1 January 1866, the western district of Lom (population: 2,691) was separated and established as the new municipality of Skiaker. Afterwards, the remaining part of Lom had 3,299 residents. The boundaries of Lom have not changed since that time.

The municipality (originally the parish) is named after the old Lom farm since the first Lom Stave Church was built there. The Old Norse form of the name was Lóar (nominative case) and Lóm (dative case). The name is derived from the plural form of ló which means "clearing" or "meadow".

The coat of arms was granted on 6 February 1987. The official blazon is "Azure, three shovels argent palewise in fess" (Norwegian: På blå grunn tre sølv skjeltrekor). This means the arms have a blue field (background) and the charge is three vertical spades lined up horizontally. The charge has a tincture of argent which means it is commonly colored white, but if it is made out of metal, then silver is used. These spades (Norwegian: skjeltrekor) were historically used to scoop water from the irrigation channels typical for the area. The area is one of the driest in Norway, but the soil is good for agriculture. It thus needs irrigation. In the 17th century, a system was developed in which melting water from the mountains was transported to the area using wooden channels or aqueducts. The water was further divided using irrigation channels. The arms were designed by Einar H. Skjervold. The municipal flag has the same design as the coat of arms.

The Church of Norway has three parishes (sokn) within the municipality of Lom. It is part of the Nord-Gudbrandsdal prosti (deanery) in the Diocese of Hamar.

An ancient trade route passed up from Sunnmøre through Lom and Skjåk and down the Gudbrandsdalen valley into Eastern Norway. The trade consisted of fish and salt heading inland, and grain heading to the coast.

The Saga of Olaf Haraldson relates that St. Olaf commented as he first looked down on Lom, "What a pity to have to lay waste to such a beautiful valley." In the face of such a clear motivation, the residents of the valley converted (it has since been a recurring discussion whether he looked to Lom or the neighbouring municipality Skjåk, at the time a part of Lom.) St. Olafs-stuggu, a building where St. Olaf is reported to have spent a night in 1021, can still be found here. The building is part of the Presthaugen District Museum.

Lom Stave Church, which is located in Fossbergom, is believed to have been built in 1158, making 2008 the 850th anniversary. It was enlarged in 1634, with further addition of two naves in 1667. It is believed that the church was originally surrounded by a circumambulatory passage, like many other Norwegian stave churches, but that this passage was removed when the two side wings were added. A few Runic inscriptions can be still be seen in the church. The church also contains numerous paintings from the 17th and 18th centuries with religious motifs. Many of the paintings were made by local artist Eggert Munch, a distant relation of the famous Edvard Munch. The church also contains numerous examples of local woodcarving, as seen in the elaborate acanthus scrolls adorning the pulpit. Carved dragon figures on the roof are old symbols of protection against evil. It is still in use as the local church.

The Garmo Stave Church, which was built around 1150, has been relocated from Lom municipality and is now at Maihaugen in Lillehammer. It was replaced with a new Garmo Church.

During the 1940 Norwegian Campaign German prisoners of war were kept by the Norwegian Army at Lom prisoner of war camp. Lom was bombed twice by the German Luftwaffe in April 1940.
