The flag of the state of Coahuila is, like most current Mexican state flags, the coat of arms centered on a white field.
The coat of arms was approved by the state's congress in 1942. It is gold with at the bottom the words "COAHUILA DE ZARAGOZA", which is the state's official name.
The inner shield is divided into three sections. The top left section has a tree and two wolves, which were taken from the coat of arms of Biscay, because the cities of Saltillo, Parras and La Laguna belonged to the province of New Biscay. In the top right section there is a lion rampant on a gold field, and the words "Plus Ultra" from the shield of Badajoz, an important city in Extremadura. This refers to Coahuila's original name of New Extremadura. The lower section shows a river, a grove and a raising sun. The grove is related to the word "coahuitl" which means tree in Nahuatl. The river is the Monclova river (Monclova was the first capital of the state). The sun symbolizes that Coahuila is the birthplace of the Mexican Revolution.
