The Edmonton Oilers have a rich history, marked by periods of both dominance and rebuilding. Throughout their journey, several coaches have left an indelible mark on the franchise. Here's a look at five of the most impactful coaches in Edmonton Oilers history:

1. Glen Sather: Glen Sather is almost inarguably the most beloved and successful coach in Edmonton Oilers history. Sather served as head coach from 1977-1980 and is a legend in the team's history. He led the Oilers to their first-ever playoff appearance in 1979. From 1983 to 1988, Sather coached the Oilers to four Stanley Cup championships. In the 1985-86 NHL season, Sather received the Jack Adams Award, which is given to the NHL coach who has contributed the most to his team's success. Besides his success as a coach, Sather was also the team's general manager from 1980 to 2000, and was instrumental in building the team that won five Stanley Cups in seven years. Sather holds the record for most games coached and most wins as head coach.

2. John Muckler: John Muckler is the other coach to win a Stanley Cup as head coach of the Edmonton Oilers. Muckler was an assistant coach during the Oilers' first four Stanley Cup wins. He took over from Glen Sather as head coach in 1989 and led the team to their fifth championship in 1990. In the Oilers' all-time list of coaches, Muckler ranks fifth with 75 wins during the regular season, and second with 25 wins during the playoffs.

3. Craig MacTavish: MacTavish coached the Oilers from 2000 to 2009. During his time with the team, he helped develop young talent such as Shawn Horcoff and Ales Hemsky, and led the team to the playoffs four times. MacTavish was known as a tough coach who commanded respect from his players.

4. Ron Low: Ron Low coached the Oilers from 1995-1999. Before the salary cap era, Low was able to get the most out of the team. During his time as coach, Low had 139 wins and 162 losses, and he led the team to the playoffs twice. In the first round of the 1997 Stanley Cup Playoffs, Low guided the Oilers to an upset victory over the heavily favored Dallas Stars. The following season, the Oilers beat the Colorado Avalanche in Game 7 of the first round, despite being the underdog.

5. Jay Woodcroft: While his tenure was relatively short, Jay Woodcroft made a significant impact on the Oilers. Although he was recently replaced as head coach, some believe Woodcroft may be considered the best coach in Edmonton Oilers history.
