The original Newtown station opened on 26 September 1855 with the opening of the Main Suburban line.
It was located to the west of King Street, about where the former Crago's Flour Mills now stand.
Mortuary facilities were provided from 1875.

The line through Newtown was quadruplicated in 1892, and a new station was built at the present location.
This station consisted of two side platforms and an island platform in the centre.
The site of the original station became a goods yard.

In 1927 the line was further expanded to six tracks (four with electrification) and Newtown Station was demolished and replaced by the present station which served only the up and down local tracks.
The new station was opened on 29 May 1927.
The original overhead booking office was retained and its platform access was modified to serve only this new platform.
The bookstall for NSW Bookstall was constructed in 1937.
In c. 1975 the original roof of the platform building was removed and replaced with a lower profile roof.
In 1989 the station was refurbished.

On 29 October 2012, a new entrance to the station was opened, constructed as part of a major upgrade to the station and surrounding precinct.
The upgrade work included demolition of the existing platform building, replacing the platform surface and canopies, and the construction of a new concourse featuring lifts and enhanced stair access to the platform.

The existing access to the platform, via a single narrow flight of stairs connected to a heritage entrance building on King Street, was closed but retained as an emergency exit.

Several buildings were refurbished and converted to retail use, including the former entrance building.
