Joseph Henri Richard (February 29, 1936 – March 6, 2020) was a Canadian professional ice hockey player who played centre with the Montreal Canadiens in the National Hockey League (NHL) from 1955 to 1975. 

He was nicknamed "Pocket Rocket" after his older brother, Canadiens' legend and fellow Hockey Hall of Famer Maurice "Rocket" Richard. Henri won the Stanley Cup 11 times as a player, the most in NHL history. 

Richard and Bill Russell of the National Basketball Association are tied for the record of the most championships won by an athlete in a North American sports league. In 2017, Richard was named one of the '100 Greatest NHL Players' in history.

Henri Richard began his professional career playing on the same team as his older, more famous brother; and comparisons between himself and his brother were easy to make. He was nicknamed "Pocket Rocket" while still a junior in reference to his brother's nickname "Rocket Richard," as well as the fact that Henri Richard was shorter than his brother.

The two Richard brothers' style of play was quite different. Maurice Richard was famous for driving at the net with brute force; however, Henri Richard preferred tactical playmaking and outthinking the opponent. Maurice shot left; Henri shot right. 

Maurice was a goalscorer who was the first to score 50 goals in 50 games, and led the league in goals on five occasions; Henri led the league in assists twice, in 1957–58 and in 1962–63. Maurice was strong; Henri was fast. However, they had one thing in common: both were willing to be physical on the ice.

Initially, Montreal Canadiens coach Toe Blake kept the two Richard brothers apart on the ice, fearing that his star Maurice Richard would give up goalscoring opportunities to his younger brother. 

However, one game against Chicago a couple of injuries forced Blake to play the Richard brothers together, and Henri assisted Maurice on a goal in the third period, and from then on he played the brothers together on a line with hall-of-famer Dickie Moore.

Toe Blake later said that playing with Henri forced Maurice to become a better player, and helped prolong Maurice's career. Later in 1958, when Maurice Richard was injured, Toe Blake moved Marcel Bonin to the line to take Maurice's place, and Henri Richard's line continued to produce goals, showing the world that Maurice Richard was not simply carrying his little brother.

The Canadiens won the Stanley Cup in each of Henri Richard's first five seasons, the longest championship streak in NHL history. Maurice Richard retired after the last of these titles in 1960, however even before then Henri Richard was recognized as a star in his own right. 

In 1957–58, he was named to the first All-Star team and in 1959 he was named to the second All-Star team; he was also named to the second All-Star team in 1961 and 1963. 

He scored the Stanley Cup-clinching goal at the 2:20 mark of the first overtime of game six in the 1966 Stanley Cup Finals against the Detroit Red Wings, when a pass bounced off of Henri Richard's body into the net while Detroit's goalie Roger Crozier was still sprawled out on the ice. 

In the 1971 Stanley Cup Finals, Richard scored the game-tying and Stanley Cup-winning goals in Game Seven against the Chicago Black Hawks.
