The Texas Credit Union League (TCUL) is a not-for-profit credit union league that publicly represents nearly 600 credit unions within the state of Texas. It communicates with and educates the general public on credit unions as a safe and secure financial institution, provides professional development to practitioners in the industry and advocates for the credit unions on a state and federal legislative and regulatory level. More than 7 million members in turn own these credit unions, with TCUL's service corporation providing industry assistance and tools (such as financially related products and services, education and assistance grants, marketing communication resources, educational and training options, and more) to help spread their presence as full-service financial institutions.

The Texas Credit Union League was incorporated on October 6, 1934, in the Hotel Texas in Fort Worth, now the Hilton Fort Worth.

Since its organization, TCUL's vision statement ensures that TCUL will "be the essential partner for credit union success."

Further building upon this principle, TCUL's mission statement proclaims a goal "to protect credit unions, and promote their growth, strength and unity. TCUL currently employs approximately 130 employees, with the majority being "out in the field," to make sure their vision and their mission reach as large an audience as possible.

In recent years, TCUL has been an active participant in promoting the credit union philosophy of "people helping people" both on a local and on a state level. TCUL achieves this through efforts with the 501(c)3 public charity, the Texas Credit Union Foundation (TCUF), including educational grants, financial literacy programs and more, or through providing training opportunities, chapter meetings, council meetings and various other awareness-raising activities.

In 2006, the Texas Credit Union Foundation received a grant from the National Credit Union Foundation to implement a state-legislated financial education program for high school students. The project enables teachers in Texas school districts to deliver financial education curriculum.

Additionally, TCUL has been an active provider of disaster recovery relief materials for its credit unions that may find themselves the victim of unexpected environmental causes. Most recently, in August and September 2008, hurricanes Gustav and Ike were under strict monitoring by the TCUL staff. Updates were posted on TCUL's homepage with e-mails circulating among employees and members to ensure their safety and awareness.

As a result of Hurricane Ike's destruction along the Southest Texas coast, many families and workers within the credit union movement found themselves needing substantial assistance and relief efforts. TCUL began their charity relief "Adopt-a-Family" program in October 2008 as a means of providing these families in need achieve a sense of stability and hope for the holidays.
