Piedras Negras (Spanish pronunciation: [ˈpjeðɾas ˈneɣɾas] lit. 'Black Rocks') is a city and seat of the surrounding municipality of the same name in the Mexican state of Coahuila. It stands at the northeastern edge of Coahuila on the Mexico–United States border, across the Rio Grande from Eagle Pass in the U.S. state of Texas.
In the 2015 census the city had a population of 163,595 inhabitants, while the metropolitan area had a population of 245,155 inhabitants. The Piedras Negras and the Eagle Pass areas are connected by the Eagle Pass–Piedras Negras International Bridge, Camino Real International Bridge, and the Union Pacific International Railroad Bridge.
In English, Piedras Negras translates to 'black stones' – a reference to coal deposits in the area. Across the river, coal was formerly mined on the U.S. side at Dolchburg, near Eagle Pass. This mine closed around 1905, after a fire. Mexico currently operates two large coal-fired power stations named "José López Portillo" and "Carbón 2" located 30 miles (48 km) south of Piedras Negras. These two coal-fired power plants are currently operated by Comisión Federal de Electricidad, the state-owned Mexican electric utility.

History
On June 15, 1850, a group of 34 men (commanded by Andrés Zapata, Gaspar Salazar and Antonio Ramírez) met with Colonel Juan Manuel Maldonado to give the news that they had created a pass point at Piedras Negras, to the right of the Rio Grande, south of Fort Duncan. They named it Nueva Villa de Herrera, but it later became Villa de Piedras Negras. In Otto Schober's "Breve historia de Piedras Negras," the local historian points out that the 34 men were repatriates (Mexican Americans) who arrived on June 15, 1850, in what was then called "Colonia Militar de Guerrero en Piedras Negras."
In 1855, the town was looted by a small force of 130 Texans that had been organized by Texas slaveholders for a punitive expedition against a nearby border settlement the Texans claimed contained fugitive slaves and Native Americans. The force was led by a captain of the Texas Rangers. As it happened, the incursion was opposed and "repelled by a superior force of Negroes, Native Americans, and Mexicans who were waiting in ambush" inside Mexico. But the Ranger-led expedition then looted Piedras Negras while returning to Texas.
Following the discovery of huge deposits of coal in the region, in 1881 a railroad track was begun that was completed in 1883. The regional economy flourished and on December 1, 1888, it was granted city status; this time with the name of Ciudad Porfirio Díaz. After the fall of Diaz in 1911, the city reverted to being named Piedras Negras.
On April 26, 2004, flooding killed 31 people with up to 60 reported missing.
On April 24, 2007, an F4 tornado struck the city, killing three people there and seven in Eagle Pass, Texas.
From June 14–15, 2013 over 10,000 homes were damaged by flooding and one person was killed.
On the night of June 8, 2018, former Piedras Negras mayor Fernando Purón was shot in the back of the head by an unknown man while Purón was taking a selfie with an admirer. Purón died on the spot, becoming the 112th candidate or politician to be killed since Mexico's electoral campaign began in September 2017. Purón was supposed to run in the 2018 Mexican election on July 1 as a congressional candidate of the Institutional Revolutionary Party (PRI). Sonia Villarreal, current mayor of Piedras Negras and fellow member of PRI, suspended her mayoral reelection campaign in response to Purón's murder to concentrate on her current duties, stating that "We don't (want) his name to be just one more added to the list of candidates who have been victims of these deplorable acts."
