Alajärvi Church, also known as the Church of Gabriel (Finnish: Gabrielin kirkko), is the main Lutheran church in the city of Alajärvi, Finland.^[1]

The church was designed by the leading architect operating in Finland at the time, Carl Ludvig Engel, completed in 1836 and consecrated in 1841.^[1][2] It is designed in the neoclassical style, and constructed of timber, under a tarred wood shingle roof. There is a standalone bell tower next to the church.^[1]

The main altarpiece was created in 1907^[3] by the Finnish, Alajärvi-born^[4] post-impressionist artist Verner Thomé, and depicts Jesus's agony in the Gethsemane.^[2]

In 1896, the church was refurbished, adding an internal balcony with seating, bringing the total seating capacity to 1,200, although in its current configuration it seats c. 1,000.^[1]

The church, along with the city centre public and administrative buildings complex designed by the Finnish architect Alvar Aalto, has been designated and protected by the Finnish Heritage Agency as a nationally important built cultural environment (Valtakunnallisesti merkittävä rakennettu kulttuuriympäristö).^[5]
