George Seymour Lyon
(July 27, 1858 – May 11, 1938)
was a Canadian golfer, and has been
honoured in Canada's Sports Hall of Fame. 

Lyon was born in Richmond, Ontario.
His early sporting career was in cricket. 
Although he began playing golf at the age of 38, he won the gold medal in golf in the
1904 Summer Olympics in St. Louis, Missouri.
He won the Canadian Amateur Championship eight times between 1898 and 1914,
and won the Canadian Seniors' Golf Association Championship ten times
between 1918 and 1930.

Lyon lost in the finals of the
1906 U.S. Amateur Championship,
and in the semi-finals of the
1908 British Amateur Championship.

He travelled to London, England,
in 1908, to defend his Olympic title,
but plans to stage a golf tournament
there were cancelled at the last minute,
and golf has not been held in the
Olympics since, although it has been reinstated as an Olympic sport for the
Olympic Games in 2016.

In 1955, Lyon was inducted into
Canada's Sports Hall of Fame.
In 1971, he was inducted into the
Canadian Golf Hall of Fame.
