The denomination known as the United Christian Church is a small evangelical body of Christians with roots in the Radical Pietistic movement of Martin Boehm and Philip William Otterbein. This group may often be confused with local congregations and churches of other denominations that also use the name United Christian Church. According to a study conducted by the Association of Statisticians of American Religious Bodies, the United Christian Church had 11 congregations with 770 members in Pennsylvania in 1990.
