Houston is one of the cities in Texas with the largest Korean population, and the Korean church community is very active.

The Houston Korean Church serves as a center for immigrant support, information sharing, and community solidarity, going beyond just a religious institution. In particular, Presbyterian churches have the longest history among Korean churches and have formed stable communities. The Houston Korean Presbyterian churches are primarily located in the Memorial, Braeswood, and Katy areas to the west of the city.

The Houston Korean Presbyterian Church is one of the oldest churches among the Korean churches in Houston. There are several churches affiliated with the Presbyterian Church in the Republic of Korea (both the Hapdong and Tonghap denominations) throughout Houston, continuing the tradition of faith that has been passed down from the first generation of Korean immigrants. While maintaining traditional Presbyterian worship formats such as Sunday services, Wednesday services, and early morning prayers, many also operate separate English worship services for the second and 1.5 generation Korean Americans. These English services are conducted with contemporary worship music and English sermons, supporting the faith life of the generation that has grown up in the U.S.

Houston Onnuri Church is a branch of Onnuri Church in Seoul, where immigrants, students, and expatriate families actively gather. It provides a familiar worship atmosphere and Korean church culture for families who have recently immigrated from Korea, serving as an initial settlement network for newly arrived Koreans in Houston. The praise team is of high quality, and various cell meetings and small group activities are actively conducted.

The network of Korean Presbyterian churches in Houston is connected through the Texas Presbytery. This network facilitates exchanges of pastors, youth joint retreats, and co-hosting of Vacation Bible Schools (VBS) among the churches. In particular, the operation of Korean Language Schools within the churches plays an important role in teaching Korean language and culture to second-generation children born in the U.S. Korean language classes are offered on weekend mornings, allowing Korean parents to attend worship while their children receive Korean education.

The Korean Presbyterian churches in Houston are also active in community service. They conduct food sharing, immigrant legal seminars, job information sharing, and health screening events in church spaces, fulfilling the practical needs of the Houston Korean community. Texas has a favorable environment for religious activities, making church-based community activities particularly vibrant. For newly settled Koreans in Houston, visiting nearby Korean churches, regardless of denomination, often becomes a quick way to settle in. Church information can be found on the Houston Korean community app or Korean portal sites.
