William Kemmeller Verbeke (July 18, 1820 – February 23, 1898) was an American businessman, philanthropist, early developer of Harrisburg, Pennsylvania and politician who served as a City Controller, School Director and Mayor of Harrisburg.

After initially investing his 1856 inheritance from his late father in land adjacent to downtown Harrisburg, he began developing a new ward of the city.

In what he first called "West Harrisburg" (present day Midtown) due to the orientation of the maps at the time, he developed a neighborhood built by and sold to very low income residents; this area would come to be known briefly as "Verbeketown" until annexed into the newly incorporated city in 1860.

[1] Verbeke helped to organize and serve as Presiding Officer of the Good Will Fire Company No.

[3][4] When the Confederate States Army first invaded Pennsylvania during the American Civil War, the Harrisburg Daily Patriot And Union, which regarded Verbeke as "one of our best and known and most highly esteemed citizens," reported that he immediately organized and promised wages to a group of thirty-six men and three wagons known as the Verbeke Guards to muster at Camp Curtin under Col. Asbury F. Awl's 201st Pennsylvania Infantry Regiment.
