OiC is an international evangelical church in Oslo welcoming people from all backgrounds.

OiC (Oslo International Church) is an international evangelical church founded in 2004 in Oslo, affiliated with the Norwegian Missionary Society, a Lutheran mission organization. The congregation welcomes people from a wide range of Christian denominations, nationalities, and backgrounds, viewing cultural differences as positive resources that enrich the community. Services on Sundays are held in English, while weekday growth meetings take place in homes, and the Sunday School, OiC Kids, operates in both Norwegian and English. The church draws its theological basis from the Reformation and the Apostle's Creed, seeking to be cross-denominational and inclusive of all who are curious or seeking faith. OiC emphasizes building community through hospitality, fellowship around tables such as Holy Communion and church coffee, shared prayer, and generosity of time, skills, and resources. The congregation consists of people of varying ages, life stages, and cultures who gather to worship, pray, learn, and grow together in this specific time and place, supporting one another through transitions and seasons of life.
