Tilden is an unincorporated community in and the county seat of McMullen County, Texas, United States.
Tilden lies at the intersection of State Highways 16 and 72 in the north central part of the county. It is located roughly an hour south of San Antonio.
In 1871 John C. Ross, the district clerk of Live Oak County, established the first county court in Dogtown and Dogtown's name was changed to Colfax. The court met for about five months and was disbanded, because the people in the county refused to use it. Until 1876 all legal affairs were conducted in Oakville through the Live Oak County Courts. All records prior to this time are found in Live Oak County and some in Atascosa County. In 1873 a petition was signed by 153 citizens requesting that the county be organized, but it wasn't until 1877 that the county became officially organized. Once organized, Colfax was formally surveyed and the town's name was changed to Tilden and chosen as the county seat. The town was named after the 1876 Democratic presidential candidate Samuel J. Tilden, then governor of New York, who arrived in town on the stagecoach during his campaign trail to speak to the local citizens. Mr. Tilden never became president, but lost the presidency to Rutherford B. Hayes.
By 1876 it had four general stores, one grocery store, two saloons, a drugstore, and a hotel. In 1879 a ferry across the Frio was established at Tilden, and about 1,880 stagecoaches traveling the San Antonio-Laredo road began to make regular stops there. In 1878 the town's first church was built and was shared by Methodists and Baptists. Soon afterward, a Catholic church was also constructed, and in 1881 Tilden became the home of McMullen College. John Van Epps Covey taught there for a while. During the late 1880s and early 1890s camp meetings were also held at Tilden. In 1884 the settlement was described as a "post village" with about 250 residents, but it had the two churches, the college, a blacksmith, a cabinetmaker, two druggists, and the Tilden Ledger, a weekly newspaper. By 1890 the town had grown to 600 residents.
In 1896 Tilden's population was 450, and in 1900 it was 506. In 1897 McMullen College was formally dissolved. By 1933 the town had a population of 250 and four businesses. In 1939, possibly because of new oil production in the county, 500 people and fifteen businesses were reported. The population remained stable at 500 during most of the 1940s. In 1947 the town had ten businesses. In 1949 it had 380 people and ten businesses. In 1952 Tilden had three cafes, four service stations, two garages, four grocery stores, a drugstore, a barbershop, a lumberyard, and three churches. The 2000 census puts the population at 600.
