Ladonia is a town in Fannin County, Texas, United States. Its population was 597 at the 2020 census.
The area was first settled around 1840. Originally called McCownville, its name was changed to Ladonia in 1857, supposedly in honor of A. T. Donitz. Its population grew late in the 19th century when the Gulf Colorado Santa Fe Railroad[4] went through Ladonia, making it a shipping point for corn, cotton, and grain crops. Because of this, the population increased rapidly to 1,500 in the 1890s and peaked at over 2,000 by the turn of the 20th century. However, Ladonia suffered during the Great Depression. At a population of 1,199 thereafter, it never recovered, but continued to decrease in population, falling to 658 in 1990[5] and 612 in 2010.
