ECW Press is a Canadian book publisher located in Toronto, Ontario.

ECW Press publishes a range of books in fiction, non-fiction, poetry, sport, and pop culture.

It started with two principal series: the Annotated Bibliography of Canada's Major Authors (ABCMA) and Canadian Writers and Their Works (CWTW).

Through the 1980s, ECW upgraded its typesetting facilities, published reference titles and began to service third-party clients, creating books for corporations to use for promotional purposes and events such as anniversaries.

In the 1990s, ECW re-commenced trade publishing and expanded its scholarly and reference lines for high school and public libraries.
