The County of Frontenac, also known as Frontenac County, is an upper tier municipality in the Canadian province of Ontario.

Frontenac County does not have a county road system, nor does it manage social services beyond a limited scope as outlined by the province. While new development does require board approval, the board does not have the ability to outline new development themselves.

The County has a land area of 3,220 square kilometres. The population in 2001 was 24,411 and in 2006 it was 26,658.
