Mineral Wells is a city in Palo Pinto and Parker Counties in the U.S. state of Texas. The population was 14,820 at the 2020 census. The city is named for mineral wells in the area, which were highly popular in the early 1900s.

In 1919, Mineral Wells hosted the spring training camp for the Chicago White Sox, the year of the famous "Black Sox" scandal involving "Shoeless" Joe Jackson. Mineral Wells also hosted spring training for the Cincinnati Reds and St. Louis Cardinals in the 1910s and early 1920s. The baseball field was located in the center of town.

Mineral Wells military history dates back to 1864 with the organization of Company 1, 4th Texas Infantry. By January 1925, the War Department approved the site that would become Camp Wolters, the training ground for the 56th Cavalry Brigade of the Texas National Guard.

In 1956, the base began operations as the Primary Helicopter Center of the United States Army that would provide basic training and primary flight training for all rotary-wing aviators. The Vietnam War created an increased need for pilots. To meet the demand, Fort Wolters increased operations to become the training site for helicopter pilots for the Marine Corp in 1968 and the Air Force in 1970. Nearly every helicopter pilot that flew in Vietnam was trained at Fort Wolters.

Fort Wolters was deactivated in 1973. The 8,500 acres was then parsed out to the city of Mineral Wells, private businessmen, Weatherford College, and Lake Mineral Wells State Park.

Mineral Wells is very well known for the state park which features fishing, camping, horse riding, biking, hiking trails and rock climbing. One attraction is Penitentiary Hollow, a popular rock climbing area.

Mineral Wells lies east of the Brazos River and Palo Pinto Mountains.

According to the United States Census Bureau, the city has a total area of 21.2 square miles (54.9 km), of which 20.5 square miles (53.0 km) are land and 0.7 square mile (1.9 km) (3.45%) is covered by water.

The Texas Department of Criminal Justice (TDCJ) operates the Mineral Wells District Parole Office in Mineral Wells. The Corrections Corporation of America (CCA) operated the Mineral Wells Pre-Parole Transfer Facility in the Fort Wolters Industrial Park on behalf of the TDCJ. It closed in August 2013. The correctional facility, which had been operated by CCA since 1995, is located on the property of the former Fort Wolters in Palo Pinto County and in Mineral Wells. It can house up to 2,100 prisoners. As of March 2013, its annual payroll was $11.7 million, and it was among the largest employers in Mineral Wells, with about 300 employees. On Monday March 4, 2013, the Texas Senate Senate Finance Committee voted 11–4 to close the correctional facility. Mike Allen, the mayor of Mineral Wells, criticized the closure, saying, "We'll lose right at over 300 jobs, and 300 jobs in a community of 17,000 ... is devastating. This means a lot to this community." John Whitmire, the head of the Texas Senate Criminal Justice Committee, said, "We're sitting on about 12,000 empty [prison] beds, so it just makes good business sense ... that we not operate it, and we take those savings and plow them back into additional public-safety programs."

The United States Postal Service operates the Mineral Wells Post Office. Zip codes are 76067 and 76068.
