Hiddenite is a census-designated place (CDP) in east-central Alexander County, North Carolina, United States.

Hiddenite was named for William Earl Hidden (1853–1918), a mineralogist sent to North Carolina by Thomas Edison to look for platinum.

[6] The Hiddenite Gem Mines and surrounding areas also yield emeralds, sapphires, and many other precious stones.

Sluicing and digging for precious gems is a popular recreational activity that draws many visitors to the area.

In 2020, during the heavy rains of Tropical Storm Eta in the area, the Hiddenite Bridge split apart.

The event is 13.1 miles long and begins at Pleasant Hill Baptist Church; the finish line is marked in front of the Lucas Mansion.
