Fannin Battleground State Historic Site, Memorial battlefield in Goliad County, United States.

Fannin Battleground State Historic Site is a 14-acre memorial ground east of Goliad in Goliad County, Texas, marking the Battle of Coleto Creek of March 19–20, 1836. It holds a stone obelisk, an interpretive exhibit, a group pavilion and a picnic area, and is operated by the Texas Historical Commission.

The Battle of Coleto Creek was fought here on March 19 and 20, 1836, between Col. James W. Fannin's Texian forces and the Mexican Army under Gen. José de Urrea. Surrounded and outnumbered, Fannin surrendered; he and his troops were executed several days later at nearby Presidio La Bahía. Around 1913 the citizens of Goliad County donated the 14-acre battleground to the State of Texas, which first named it Fannin State Park.

Goliad County citizens donated the 14-acre battleground to the State of Texas around 1913, and it was first named Fannin State Park. The site is now operated by the Texas Historical Commission, which maintains the obelisk, an interpretive exhibit, a group pavilion and a picnic area. The surrender here led to the execution of Fannin and his troops at nearby Presidio La Bahía.

The site lies east of Goliad, reached via Highway 59 in Goliad County. The Texas Historical Commission operates it, and the grounds hold a stone obelisk, an interpretive exhibit, a group pavilion and a picnic area. Visitors can walk the 14-acre battlefield on foot; the pavilion shelters groups, and the picnic area allows a stop before continuing to Presidio La Bahía.

The site's first memorial was not the stone obelisk but an iron cotton gin screw placed in 1891 by local resident William Hunter. The obelisk came later, after Goliad County citizens donated the 14-acre battleground to the State of Texas around 1913.
