Lamar is a small, unincorporated community and census-designated place (CDP) in Aransas County, Texas, United States, 10 miles (16 km) north of Rockport and 40 miles (64 km) north of Corpus Christi. As of the 2020 census, Lamar had a population of 724. The community was named for Mirabeau B. Lamar, the second president of the Republic of Texas. This was a new CDP for the 2010 census.

Lamar was founded in 1839 at Lookout Point, on the channel entrance to Copano Bay. President Lamar agreed to relocate the custom house here, and the town thrived as a port and the site of a salt works. This prosperity ended abruptly on February 11, 1864, when the town was bombarded and practically obliterated by the Union Navy.

The restored cemetery is a Texas historical landmark. Goose Island State Park is within the CDP.
