Martha Edwards (died 1868) was an American settler who lived in West Texas during the Wild West era. The sister-in-law of Ethan Edwards, the wife of Aaron Edwards, and the mother of Lucy, Ben, and Debby, she was killed by Comanche Indians during the Edwards Farm massacre amid the Texas-Indian Wars. It was speculated by some that she had an affair with her brother-in-law Ethan, who may have been Debby's father.
