Carex waponahkikensis, commonly known as the Dawn-land sedge, is a species of sedge first described by M. Lovit and A. Haines in 2012. It is native to a small range in the state of Maine as well as in adjacent parts of coastal New Brunswick.
Formerly known as Carex scoparia var. tesselata, it has been split from Carex scoparia based on inflorescence length, leaf blade width, and differences with the perigynium.
In Maine, the sedge is only known from Washington County and Hancock County in the eastern part of the state.
