2018–19 St. Louis Blues season

The 2018–19 St. Louis Blues season was the 52nd season for the National Hockey League franchise that was established on June 5, 1967. The Blues were in last place in the league in January, but rallied to make the playoffs. They advanced to the 2019 Stanley Cup Finals against the Boston Bruins and won in seven games, their first Stanley Cup in the franchise's 52-year history.

The Blues became the fourth St. Louis-based professional sports team to win a major championship, joining the 11-time World Series champions St. Louis Cardinals of Major League Baseball (MLB), the 1957–58 St. Louis Hawks of the National Basketball Association (NBA), and the 1999 St. Louis Rams of the National Football League (NFL). This made St. Louis the eighth city to win a championship in each of the four major U.S. sports.

Off-season
On May 30, 2018, the Blues named Mike Van Ryn as assistant coach, replacing Darryl Sydor, who stepped down to spend more time with his family. Van Ryn played the first three seasons (2000–2003) of his eight years in the NHL with the Blues, scoring 13 points in 69 games.

The Blues extended their affiliation with the Tulsa Oilers of the ECHL on May 31.

Season summary
The Blues started the season sluggish, and head coach Mike Yeo was fired on November 19 with the team's record at 7–9–3. Craig Berube, who had served as assistant coach with the Blues since 2017, was named the interim head coach. St. Louis began the 2019 calendar year with the worst record in the league; 15–18–4 and 34 points recorded. Soon after, rookie goaltender Jordan Binnington joined the team. On January 7, he won his first game in a shutout and took over as the team's starting goaltender. The Blues then went on a franchise-record 11-game winning streak and had a 30–10–5 run to finish the season. They clinched a playoff spot on March 29, 2019.

In the playoffs, the Blues defeated the Winnipeg Jets, Dallas Stars, and San Jose Sharks to advance to the 2019 Stanley Cup Finals, where they faced the Boston Bruins. It was their first Finals appearance since 1970. On May 29, 2019, St. Louis won a Stanley Cup Finals series' game for the first time in franchise history after getting swept in three previous series (1968–1970), as they defeated the Bruins 3–2 in overtime in game 2. On June 12, 2019, they defeated the Bruins in seven games to win the first Stanley Cup title in franchise history. Until then, they were the oldest franchise to have never won a Stanley Cup.

Ryan O'Reilly, who had been acquired in a trade during the previous offseason, was the Blues' top regular season scorer with 77 points. He then had a franchise-record 23 playoff points and won the Conn Smythe Trophy as the most valuable player in the playoffs. O'Reilly also won the Frank J. Selke Trophy for the league's best defensive forward during the regular season.

"Gloria"
St. Louis had been in last place in the NHL on January 3. On the night of January 6, a few Blues players were in a Philadelphia bar watching the National Football League "Double Doink" wildcard game between the Philadelphia Eagles and Chicago Bears. The DJ played the 1982 Laura Branigan song "Gloria", and according to defenceman Joel Edmundson, "this one guy looked at the DJ and said, 'Keep playing "Gloria"!' so they kept playing it. Everyone would get up and start singing and dancing. We just sat back and watched it happen. Right there we decided we should play the song after our wins." The following day, goaltender Jordan Binnington made his first start for the Blues that season and won the game with a shutout.

The team played it after every win for the rest of the regular season and playoffs, and as their hot streak continued, the song became popular in the city of St. Louis. "Gloria" was written on signs and t-shirts. The St. Louis radio station KYKY played it for 24 hours straight after series victories in the playoffs.
