The suburb was officially named in 1981, and is believed to honour George Harris (1831–1891), a Brisbane businessman. Originally in the Shire of Drayton, the suburb was first opened as the Harristown Estate in 1902, and in 1911, Harristown State School opened. From 1915 until 1993, the suburb had a functioning railway station on the Toowoomba–Wyreema line. After World War II, the area boomed.
