The first families settled Castle Shannon in 1786 in pursuit of farmland and timber and is widely assumed to be the Haas family. The most prominent farm was owned by David Strawbridge.  Following common practices of Irish settlers—primarily from Ulster—in the region to name places and farms after former or ancestral homes in Ireland, he named it Castle Shanahan.<ref>{{Cite web|url=https://www.academia.edu/4031545|title=From Rostrevor to Raphoe: An Overview of Ulster Place-Names in Pennsylvania, 1700-1820|last1=Gilmore|first1=Peter}}</ref><ref>{{Cite web|url=https://borough.castle-shannon.pa.us/the-history-of-castle-shannon/|title = The History of Castle Shannon – Castle Shannon}}</ref>

In 1872, the Pittsburgh and Castle Shannon Railroad line was completed, providing a direct link from [[Pittsburgh]] to the then-village of Castle Shannon. Development was stimulated by two years of free transportation and lumber transport given to anybody building a home.<ref>[http://www.post-gazette.com/pg/04221/352632.stm Allegheny County Municipalities], ''[[Pittsburgh Post-Gazette]]''; retrieved May 15, 2016.</ref>

In 1877, a second railroad was built from [[Finleyville, Pennsylvania|Finleyville]] through Castle Shannon to the [[West End (Pittsburgh)|West End]] neighborhood of Pittsburgh. In 1909, the right of way through the valley containing Castle Shannon was purchased by the Pittsburgh Railroad. This helped lead to Castle Shannon becoming a center for coal mining, with eight mines in operation in 1904. The [[Pittsburgh and West Virginia Railway|Pittsburgh and West Virginia Railroad]], still active today, came shortly afterward.

The First National Bank in Castle Shannon was the site of a much publicized bank robbery in 1917. $18,500 was taken in the robbery, of which $10,500 was immediately recovered from one man shot during the escape. The full sum was never recovered. A group of men gathered to chase down the robber to no avail. From that group, Elmer J Zeiler, a WWI Medal of Valor winner from the US and France, and a double Purple Heart recipient, was named the first Chief of Police in Castle Shannon when the police department was formed.

Castle Shannon was incorporated as a borough in 1919, formed from parts of [[Baldwin Township, Allegheny County, Pennsylvania|Baldwin Township]], [[Mt. Lebanon, Pennsylvania|Mt. Lebanon]], and [[Bethel Park, Pennsylvania|Bethel Township]].
