Niels Høegh Brønnum (January 5, 1882 – 1966) was a Danish missionary and physician who served in Northern Nigeria from 1913 to 1950. He is regarded as the founder of the Lutheran Church Christ in Nigeria, a novel Church in Nigeria that would eventually go on to have its councils run by Nigerian elected councilmen and pastors. Throughout his missionary career, he participated in the construction of the first medical facilities, hospital, biblical schools, secondary schools, and the incorporation of a Christian curriculum in the Adamawa Region. He took the position of Secretary to the Danish mission in 1922 where his influence continued to spread in Nigeria, and was eventually honored by many Nigerian Christian fellows. Brønnum's achievements include translating the Gospel of Mark into the traditional Bacama language and receiving Danish Knighthood in 1950 for 37 years of service to the mission. His evangelistic work was coupled with the medical skills and techniques that he brought to the natives of Northern Nigeria.
