NHL Power Players[1] (also known as Esso Power Players) was a hockey trading card scheme dreamed up by Imperial Oil (owner of the Esso brand) and the NHL Players' Association (NHLPA) in the 1970–71 hockey season.

Two albums were available, the standard (paperback) issue and a deluxe (hardcover) edition.

The front cover of the softcover album reads in French: "NHL Les Grands Du Hockey Album" and in English: "NHL Power Player Saver".

At the end of the season, it was possible to write to Esso to order any cards one did not have.

These additional stickers showed the games, goals, assists, points, and penalty minutes for each player.
