Willacy County is a county located in the U.S. state of Texas. As of the 2010 census, its population was 22,134.  Its county seat is Raymondville.  The county was created in 1911 and organized the next year. 
Willacy County was formed in 1911 from parts of Cameron and Hidalgo counties and originally included what is now Kenedy County; it was named for state senator John G. Willacy. Kenedy was split from Willacy in 1921, when the long-settled ranchers of the northern (Kenedy) part of the county sought to separate from the newly arrived farmers of the southern part.
The Bermuda onion was introduced to Willacy County in 1912. It grew well and slowly displaced ranchland in the southern part of the county, becoming the most important crop. For many years the town of Raymondville held an annual Onion Festival, using the tag line, "The Breath of a Nation." In 1940, the first oil wells were sunk in the county's Willamar Oil Field; today oil production is a major part of the local economy, although increasingly eclipsed by natural gas. Also in the 1940s, sorghum was introduced to the county, gradually displacing cotton and other crops. Cattle ranching remains a substantial economic activity as well.
According to the U.S. Census Bureau, the county has a total area of 784 square miles (2,030 km2), of which 591 square miles (1,530 km2) is land and 194 square miles (500 km2) (25%) is water.  It borders the Gulf of Mexico.

The elected officials of the tiny county, recently, have been entangled in a series of political controversies. Amongst other things, the District Attorney has sought the removal of the local sheriff, county clerk, and district clerk. Meanwhile, the Sheriff and the two clerks have petitioned the district court for the removal of the District Attorney. More recently, the District Attorney has gained even more attention for his actions concerning the dismissal of a Capital Murder charge against a confessed assailant because of, he claimed, an appropriate time to prepare. However, he found time to file, the very next day, a petition for the removal of the County Judge.
Indictments have not yet been made public and a district judge still has to sign the indictments. Two state district judges were also indicted along with State Senator Eddie Lucio, Jr.
