Alva Pearl Barrett (April 12, 1878 – March 23, 1953) was a Texas politician and businessman.

Before his father moved to Texas, he was an ordained minister of Primitive Baptist Church and a farmer.

During this time he acquired and formed many businesses, including the Texas-Louisiana Power Company.

Through the power company, Barrett was able to meet and hire C. R. Smith, whom at the time was a young accountant.

In 1928, Barrett purchased Texas Air Transport and named Smith as the secretary and treasurer of the firm.
