The Borough of Alburtis was incorporated on May 9, 1913 by the merger of two villages, Alburtis and Lock Ridge, both of which were settled in the mid-1800s.
The village of Alburtis was named for Edward K. Alburtis, a civil engineer involved in the construction of the East Pennsylvania Branch of the Philadelphia and Reading Railway. When a railroad station was established in the village in 1859, the railroad's Board of Directors named it in his honor.
A tract adjacent to Alburtis was purchased by the Lockridge Iron Company for the construction of iron furnaces in the late 1860s.
