Zebulon Montgomery Pike, namesake of Pike County and Zebulon GeorgiaBoth the county and the county seat were named after the famous explorer, Zebulon Montgomery Pike. Pike's expedition in 1805 tried unsuccessfully to follow the Mississippi river to its source. This was the same expedition in which he discovered Pike's Peak in Colorado. Throughout the United States, there are at least 14 other cities, townships, or counties named after Mr. Zebulon Pike.

Pike County's first courthouse was a simple wooden building. Then in 1825, a brick courthouse was erected on the public square after Zebulon was designated as the county seat. The current Pike County Courthouse is the pride of downtown Zebulon. Designed by Golucke & Stewart in the Romanesque Revival/Colonial Revival style, this courthouse was built in 1895 and is listed on the National Register of Historic Places.

The primary industries in Pike County include agriculture and forestry, although a 148 acre business park on highway 19 in Zebulon was established in the year 2000 to accommodate the growth of other industries as well.
