The United Pentecostal Church International (UPCI) is a Oneness Pentecostal denomination headquartered in Weldon Spring, Missouri. The United Pentecostal Church International was formed in 1945 by a merger of the former Pentecostal Church, Inc. and the Pentecostal Assemblies of Jesus Christ. From its founding until 1972, the organization was known as the United Pentecostal Church, when "International" was added to the organization's name.

The United Pentecostal Church International began with 521 churches and has grown to more than 45,000 churches, including daughter works and preaching points, 45,000 ministers, and a total constituency of over 5.8 million worldwide, making it the largest Oneness denomination. The international fellowship of United Pentecostals consists of national organizations that are united as the Global Council of the UPCI, which is chaired by the general superintendent of the UPCI, currently David K. Bernard.
