Yes, Raleigh is squarely located within North Carolina's Piedmont region.
The Piedmont is a broad physiographic province stretching along the eastern flank of the Appalachian Mountains from New Jersey to Alabama. In North Carolina, it occupies the central third of the state, characterized by rolling hills, red clay soils, and major urban centers.
Raleigh sits near the region's geographic center, making it a quintessential Piedmont city. The city's elevation (~300-400 ft), topography, and climate are all classic Piedmont features. Other major Piedmont cities include Charlotte, Greensboro, Durham, and Winston-Salem.
