Graha Bethany Nginden, Evangelical megachurch in Surabaya, Indonesia.

Graha Bethany Nginden is a modern evangelical church complex in Surabaya featuring a large main sanctuary and multiple supporting facilities. The site includes buildings for religious education, services, and a health center, creating a complete community facility.

Pastor Abraham Alex Tanuseputra founded the church in 1977 with his family and seven others; by 1987 it had 2,000 members. It belonged to the Indonesian Bethel Church until 2003, when the regional Bethany Indonesian Church became independent. A 20,000-seat temple was inaugurated in 2000, with renovations in 2009 planned to raise capacity to 35,000. In 2019 it briefly joined the Gereja Suara Kebenaran Injil, returning to Bethany Indonesian Church in 2022.

The name Graha Bethany Nginden combines the Indonesian word graha (building) with the Bethany name and the Nginden district of Surabaya. The congregation follows the motto "Successful BETHANY Families", and the church runs Bethany Christian School, opened in 2017, with kindergarten and elementary classes for its members' children.

The site is located in the Sukolilo district and can be reached by car or public transportation. Visitors should wear appropriate attire and check timings for different programs, as services and events occur throughout the week.

Bethany Care, the church's health centre, is open to everyone and works frequently with the Red Cross. The church also runs Bethany Christian School, a playgroup, kindergarten and elementary school founded in 2017. Senior pastor Aswin Tanuseputra was ordained by his father Abraham Alex Tanuseputra, who founded the church in 1977 with his family and seven others.
