Howe is a town in Grayson County, Texas, United States. The population was 2,600 at the 2010 census. It is part of the Sherman–Denison metropolitan statistical area.
The first settlers in the area arrived around the time of the Texas Revolution in 1836. In 1843, the last Indian battle in Grayson County was said to have been fought in the area. The first settlers of Howe were Jabez and Harriet Haning, and Jabez's brother John. They received land through the Peters colony after their arrival from Pennsylvania before 1850. The Houston and Texas Central Railway built through the area in 1873, and a railroad switch was located in the community. It was called "Summit" because at 810 feet (250 m) above sea level, it was supposed to be the highest point between the Red River and the Gulf of Mexico. In 1873, when Summit received a post office, two businesses were located at the switch - a general store and a saloon.
