Martin Boehm (November 30, 1725 – March 23, 1812) was an American clergyman and pastor. He was the son of Jacob Boehm and Barbara Kendig who settled in Lancaster, Pennsylvania. Boehm married Eve Steiner in 1753 and in 1756 he was chosen by lot to become the minister of the local German-speaking Mennonite church.

Although raised a Mennonite, he lacked the assurance of the presence and power of Jesus Christ in his life and he prayed for a heart-warming experience, to deepen his personal faith. Then one day, after many months of prayer and meditation he had an epiphany. After this, Martin preached with confidence and fervor. In 1761, Martin was advanced to the office of bishop in the Mennonite tradition.

On May 10, 1767, in a Great Meeting held at Long's Barn near Lancaster, Pa., Boehm met Philip William Otterbein, an ordained missionary to German speaking residents in America for the Reformed Church in Germany. Otterbein was so impressed with Boehm's passionate message that afterwards he embraced Boehm and declared, "Wir sind Brüder" (We are brethren). From that moment, the two were lifelong friends and companions.

In 1774, Boehm opened his home to a Methodist group that needed a place to meet. Soon the members of his family became Methodists, while he remained a Mennonite.

In 1791 Boehm donated land six miles south of Lancaster to that Methodist group to build religious buildings. That same year a church was built and named Boehm's Chapel.

In 1774, Otterbein helped a splinter group from a Reformed Evangelical church in Baltimore become the Second Reformed Evangelical Church and, with Boehm’s encouragement, he became its pastor.

Both men continued their outreach to others and both were strongly influenced by Methodist beliefs. They had a number of followers.

In 1800, after being expelled by the Mennonites for being too evangelical, Boehm and Otterbein formed the Church of the United Brethren in Christ, and they were elected the denomination's first two bishops.
