Hubbard was established when the St. Louis and Southwestern Railway (Cotton Belt) extended its tracks through Hill County from Mt. Pleasant to Waco. It was named for Richard B. Hubbard, a former governor of Texas. Agriculture had been the primary support for the economy for many years, as cotton was in abundance and the city had its own cotton exchange.
Today, most of the land is ranch land, and the Hubbard Livestock Auction provides a market for a wide area of Central Texas. During the early 1900s, Hubbard was noted for its hot mineral wells and bath houses. People came from all over Texas in search of relief from rheumatism and other illnesses. The wells are still here along with five city lakes built after discovering the mineral water.
