Santa Coloma d'Andorra, also known as Santa Coloma, is an Andorran town in the parish of Andorra la Vella, located near the Gran Valira river and 2 km away from the capital, Andorra la Vella.

To its west are the mountain villages of Aixàs, Bixessarri, and Canòlic in Andorra, and Os de Civís in Spain.

It houses a historic church that was nominated as a UNESCO World Heritage site on 22 February 1999 in the Cultural category. The Church of Santa Coloma d'Andorra is Andorra's oldest church.

The nave of the church was built in the 8th or 9th century, and the tower in the 12th century. In the church are visible remnants of murals made in the 12th century by the Master of Sant Coloma. Most of the murals were removed in 1933 and were in Berlin until 2007. These murals are now present in the Andorran Government Exhibition Hall.
