The 1918 Stanley Cup Final was contested by the National Hockey League (NHL) champion Toronto and the Pacific Coast Hockey Association (PCHA) champion Vancouver Millionaires. In a series held entirely in Toronto, the Toronto team won the series by three games to two in the best-of-five game series to win the Stanley Cup. It was the first series contested by the new NHL and subsequently the first Stanley Cup win by the Toronto NHL franchise team.

As with the three previous NHA-PCHA Cup Final series, the series alternated between the NHL champion and the PCHA champion each year, while the differing rules for the leagues alternated each game. This meant that all of the games for the 1918 championship series were played at Toronto's Arena Gardens.

Two of the major differences between the two leagues' rules proved to be a major factor in the series. The PCHA allowed forward passing (adopted in the 1913–14 season) and played with seven players per side; the NHL did not adopt forward passing until the following season, and only played with six players. In every game, the winner was the one playing under its league's rules. The Torontos won Games 1 and 3 with victories of 5–3 and 6–3, and the Millionaires recorded 6–4 and 8–1 wins in Games 2 and 4. Because game five was played under NHL rules, it helped Toronto's Corbett Denneny to score the series winning goal in a 2–1 victory. The Torontos outscored the Millionaires by a combined total of 13–7 in the three games played under NHL rules. Conversely, Vancouver recorded a 14–5 margin in the games under PCHA rules.

Toronto goaltender Hap Holmes recorded a 4.20 goals-against average during the series, while Alf Skinner led Toronto with eight goals. Cyclone Taylor scored nine goals for Vancouver.
