Teacup is on U.S. Highway 377 eight miles northeast of Junction in eastern Kimble County.
Teacup was probably named for 200-foot-high Teacup Mountain, located just to the west, which is said to resemble an inverted teacup. Between 1933 and 1947 the agriculture-based community claimed a population of ten and a general store. At one time a voter's precinct called the Teacup Box was organized, and the post office may have been located in the general store run by Tom Walton. Teacup acquired a school no later than 1935; it may have held classes into the 1950s. No population has been listed for Teacup since 1947.
