The West Line Historic District is a residential community in central Austin, Texas, United States.

[2] The district comprises more than twenty-five subdivisions platted between 1871 and 1948, out of the George W. Spear League and Division Z of the government lands west of the original city center.

Early settlement in the area consisted of expansive estates, later subdivided in response to the city's burgeoning population.

Due to the piecemeal development and hilly topography of the area, the streets form an irregular rectilinear grid.

A number of notable nineteenth-century residences and institutional buildings exist throughout the district, but the preponderance of resources consist of Craftsman and Classical Revival-influenced bungalows built during the height of the area's development from the 1910s-1930s.
