David Lorne Steen (born 2 January 1942)[1] is a Canadian former track and field athlete who specialised in the shot put.

He was coached by Bill Bowerman within the Oregon Ducks track and field program and was part of the winning team for the 1962 American collegiate NCAA title.

A native of Burnaby, British Columbia,[2] he became interested in athletics through the exploits of his older brother Don Steen, who became the national decathlon champion in 1955.

[3] At Burnaby South Secondary School he established himself as one of Canada's best young throwers by setting a national age-group record in the shot put.

[5] Steen grew to be a tall man, at six-foot and four and a half inches, and as his physique developed he reached a weight of 235 pounds.

[7] This earned him his first major international call-up for the 1962 British Empire and Commonwealth Games, held in Perth, Western Australia.

[1][7] The 1966 British Empire and Commonwealth Games in Kingston, Jamaica saw Steen became Canada's first ever shot put gold medallist at the competition.

His winning throw of 18.79 m (61 ft 7+3⁄4 in) was a large improvement on the Commonwealth Games record set by Lucking four years earlier.

[1][7] He came close to that seasonal peak at the 1967 Pan American Games, which were held on home turf in Winnipeg, Manitoba, Canada.

He was the bronze medallist behind two Americans who were world leaders at that point: Randy Matson, who was Olympic champion the year after, and Neal Steinhauer, the top ranked putter in 1969.

This included novelist Lawrence Hill—a keen teenage runner—whom Steen advised to focus on writing after a poor outcome of a fitness test.
