Electoral District of Drayton and Toowoomba was the original seat for the urban settlement on the eastern Darling Downs. In 1912, it was redistributed into Drayton (1912–1927), Toowoomba (1912–1960) and East Toowoomba (1912–1950).
The district elected one member from 1860 to 1878 and two members from 1878 to 1888.
The seat is notable for Member and perennial Toowoomba Mayor William Henry Groom who went on to be the region's representative at the first Commonwealth Parliament in 1901.
