The '''Queen Elizabeth Islands Subplate''' is a triangular [[tectonic block]] of the [[North American Plate]] containing the [[Queen Elizabeth Islands]] of [[Northern Canada]].<ref name="KW"></ref> It is surrounded on the south and southwest by the Parry Rift Valley, on the east by the Nares Rift Valley and on the northwest by the Kaltag Fault, which form part of the Canadian Arctic Rift System.<ref name="KW"/><ref></ref>

The Queen Elizabeth Islands Subplate formed in the mid-[[Tertiary]] during the final stages of the Eurekan Rifting Episode when a large triangular region became severed from the rest of the North American continent. It consists of a number of smaller subplates that are separated by [[fault (geology)|faults]]. The faults controlled the shapes of the subplates which in turn determined the shapes of the present day islands.<ref name="KW"/>
