Dublin is a city located in southwestern Erath County in Central Texas, United States. Its population was 3,359 at the 2020 census, down from 3,654 at the 2010 census.

The town is the former home of the world's oldest Dr Pepper bottling plant (see Dublin Dr Pepper). The plant was for many years the only U.S. source for Dr Pepper made with real cane sugar (from Texas-based Imperial Sugar), instead of less expensive high-fructose corn syrup. Contractual requirements limited the plant's distribution range to a 40-mile (64 km) radius of Dublin, an area encompassing Stephenville, Tolar, Comanche, and Hico.

Dublin was the southern terminus of the Wichita Falls and Southern Railroad, one of the properties of Frank Kell, Joseph A. Kemp, and later Orville Bullington of Wichita Falls. The line was abandoned in 1954.

Dublin was the boyhood home of legendary golfer Ben Hogan, who was born on August 13, 1912, at the hospital in nearby Stephenville. Hogan lived in Dublin until 1921, when he and his family relocated to Fort Worth.

American jurist and 1924 Texas Republican gubernatorial nominee George C. Butte married and resided in Dublin for several years and is interred there at Live Oak Cemetery.

Dublin is the birthplace of Lt. Col. George Andrew Davis, Jr., who was awarded the Medal of Honor for conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty on 10 February 1952, near the Sinuiju-Yalu River area in North Korea. Davis ranks 16th on the list of most highly decorated U.S. military personnel of all time who received the Medal of Honor.

In 2005, Governor Rick Perry signed a bill that designated Dublin as the official Irish Capital of Texas. Thus, Dublin is known to be home to many people of Irish American descent.

Each year, several events are held in Dublin.

During the week of St. Patrick's Day, the community welcomes visitors with a parade, "ambassador" pageant, and other events.

Each June during the Dr Pepper birthday celebration, Dublin celebrates its era as the oldest Dr Pepper bottling plant in the world, when it still bottled Dr Pepper with the original recipe and pure cane sugar. Following legal disputes, Dr Pepper Snapple split ties with the Dublin bottling company after 120 years of service. The newly renamed Dublin Bottling Works has become an independent company and continues to hold the birthday celebration every June.

The birthday events coincide with the Irish Stampede, a charity 10-2-4K run sponsored by the local Lions Club; the "Tour de Agua" bicycle race; and the "Gotta Love Gravel: Dublin" evening gravel ride sponsored by Dublin Bottling Works. Scores of former students from Dublin primary, middle, and high schools return at this time for the annual Dublin Area Reunion.

The community celebrates its large Hispanic population with events during Cinco de Mayo (in May) and during Hispanic Heritage month is observed in September and October.

The local Dublin Chamber of Commerce sponsors one-third of the tri-angler tournament, with a bass-fishing tournament in July held nearby at Proctor Lake. October safe trick or treating activities seek to ensure safe Halloween activities, and Christmas festivities the first Thursday in December include an annual Christmas parade.

The Double In Cowboy Church holds routine barrel races and other western-related riding events.

Throughout the year, visitors to the community enjoy seeing the five local museums—the Rodeo Heritage Museum, the Dublin Historical Museum, the Dr Pepper Museum, the National Health and Public Safety History Museum, and the renowned Ben Hogan Museum.
