Gateway Church is a non-denominational, evangelical Christian multi-site megachurch based in Southlake, Texas, near Fort Worth. As of 2023, it was ranked as the 9th largest Christian church in the United States, with attendance of 25,805. In 2024, its founding pastor, Robert Morris, resigned after his sexual abuse of a minor became public. Max Lucado, of Oak Hills Church in San Antonio, became the interim teaching pastor, and Joakim Lundqvist of Sweden also has interim pastoral duties.

Gateway Church's first service was held on April 23, 2000, at the Hilton Hotel in Grapevine. In June 2003 the church moved to Southlake Blvd. In 2010, Gateway opened its current facility, a 64-acre (26 ha) property. In 2017, Gateway Church downsized their staff by 10-15 percent. In November 2018, CBS News listed Gateway Church as the fourth largest megachurch in the United States with about 28,000 weekly visitors.

In April 2024, the church, while denying liability, settled a 2020 lawsuit brought by the family of a child who alleged that five pastors had concealed the sexual abuse she received from a youth leader in 2018.

In June 2024, the church settled with a woman who alleged in a 2023 case that she worked as an administrative assistant for a Gateway Church pastor who sexually harassed her and that the church fired her while giving the pastor two-years severance. In March 2025, Morris was indicted in Oklahoma on five criminal counts of lewd or indecent acts with a child.

On June 15, 2024, Robert Morris admitted to what he characterized as a "moral failure" involving a pre-teen girl (described by Morris only as a "young lady") that is alleged to have occurred from 1982 through 1987 when he was a young minister. This alleged serial sexual abuse occurred over a five-year period, beginning when the child was 12 years old and ending when the child was 17. This admission appeared shortly after his accuser, Cindy Clemishire, accused Morris of molesting her for four and a half years dating to December 1982, when Clemishire was 12 years old. Morris described his behavior as mere "petting" while the victim alleges eventual "rape by instrumentation" (penetration that is not intercourse). The alleged victim is now in her 50s. In a statement reportedly sent to church staff by the elders of the church, the elders said that: “Since the resolution of this 35-year-old matter, there have been no other moral failures ... Pastor Robert has walked in purity, and he has placed accountability measures and people in his life. The matter has been properly disclosed to church leadership.”

Shortly after the church elders learned additional details of the allegations, including the alleged victim's age and length of the supposed abuse, Robert Morris tendered his resignation, which was accepted. However, according to Cindy Clemishire, "Gateway received actual notice of this crime in 2005 when I sent an email directly to Robert Morris’ Gateway email address. Former Gateway elder, Tom Lane, received and responded to my email, acknowledging that the sexual abuse began on December 25, 1982, when I was 12 years old".

Evangelical Daystar Television Network announced it was removing all Robert Morris programming from its broadcast schedule. Morris's programs were broadcast every day except Saturday.

Robert Morris's son, James Morris, was the Associate Senior Pastor and had been set to take over in 2025. On the advice of lawyers, the Board of Elders as well as James Morris had stepped back to allow an investigation. Weeks later, James Morris and his wife agreed to resign from all duties at the church.
