Voksen kirke is a modern parish church located in the Vestre Aker district of Oslo, Norway. Consecrated on April 23, 1995, by Bishop Andreas Aarflot, the church serves the Voksen congregation, which was originally separated from the Røa parish in 1971. The building is a modernist “working church” (arbeidskirke) constructed primarily of red brick. It features a distinctive fan-shaped floor plan, designed by architect Arild Lauvland to create a wide but shallow space that brings the congregation closer to the altar. The church has a seating capacity of approximately 400 in the main sanctuary, which can be expanded to 500 when including the adjoining parish hall.

The interior is noted for its artistic decorations and architectural details, including exposed glulam beams and a large skylight that provides natural top-lighting. The altarpiece, titled “The Tree of Life and the Water of Life,” was created by artist Gunnar Torvund in 1998. The church also houses a 17-stop organ built by the renowned Ryde & Berg Orgelbyggeri. Adjacent to the church is the Voksen Cemetery, which was inaugurated in 1992—three years before the church itself was completed. The cemetery serves several parishes in the region and is situated on land that was formerly part of the historic Voksen farm.
