The first permanent post office in the area was established in 1840 by William Rose who named it "Roseville" in honor of his father Dennison Rose, a veteran of the War of 1812.

The village of Roseville was incorporated in 1926, and the municipal building was constructed in 1929 at Gratiot Avenue and Meier Road. This replaced the Erin Township Building that was built near the corner of 11 Mile Road and Gratiot in 1886. The 1929 building housed administrative offices as well as the police and fire departments until the 1960s, when separate police and fire stations were constructed. City offices remained in the building until 1974.

Michigan's first commercial airport, Packard Field, opened at Gratiot Avenue and Frazho Road in 1919. It was renamed Gratiot Airport in 1929, and later Hartung Field. The Eastgate Shopping Center was constructed on the site in the 1950s.

The Erin-Roseville Library was established in 1936 in one room of the municipal building. The library moved to its own building in the 1960s and into the newly constructed civic center in 1974. In 2010, it was circulating approximately 250,000 items annually.

In 1958, the village and remaining parts of Erin Township were incorporated as the City of Roseville.

An early regional mall, the Macomb Mall, opened in 1964 and is still open today, located west of Gratiot and Masonic.
