The ECCW Championship (formerly known as the NWA/ECCW Heavyweight Championship) is the top singles championship in Elite Canadian Championship Wrestling. It was first established in 1996 in the then-independent ECCW, and its name was changed when ECCW joined the National Wrestling Alliance in 1998.
