The Stanley Cup playoffs (French: Les séries éliminatoires de la Coupe Stanley) is an elimination tournament in the National Hockey League consisting of four rounds of best-of-seven series. Eight teams from each of the two conferences qualify for the playoffs based on regular season points totals. The final round is commonly known as the Stanley Cup Finals, which sees the two conference champions play for the Stanley Cup.
The NHL has always used a playoff tournament to determine its champion. Its playoff system has changed over the years, from the league's inception in 1917 when ownership of the Stanley Cup was shared between different leagues, to when the NHL took over the Cup in 1926, to the current setup today.
The Stanley Cup playoffs consists of four rounds of best-of-seven series. Each series is played in a 2–2–1–1–1 format, meaning the team with home-ice advantage hosts games 1, 2, 5, and 7, while their opponent hosts games 3, 4, and 6, with games 5, 6, and 7 being played if needed.
Eight teams in each conference qualify for the playoffs. In the playoff series format instituted in 2014, the first, second, and third place team in each of the four divisions qualify for the playoffs automatically. Two additional teams from each conference, regardless of divisional alignment, also qualify for the playoffs by having the highest point totals out of the remaining teams in the conference. These teams are referred to as the Wild Cards. Since there is no attention paid to divisional alignment with the wild cards, it is possible for a single division to produce both wild cards.
In the First Round, the eight teams are split into two separate brackets by division. Each bracket consists of the top three divisional qualifiers and one of the wild cards. The lower seeded wild card plays against the division winner with the best record while the other wild card plays against the other division winner, and both wild cards are de facto #4 seeds. The other two series match the second and third place teams from the divisions.
The winners of both First Round series advance to the Second Round. The reseeding in the previous format, which ensured the top seed would play the lowest remaining seed, was discarded. The winners of these series advance to the Conference Finals, and the winners there move to the Stanley Cup Finals.
