Gordon Meredith Lightfoot Jr. (November 17, 1938 - May 1, 2023) was a Canadian singer-songwriter and guitarist who achieved international success in folk, folk-rock, and country music.  He is credited with helping to define the folk-pop sound of the 1960s and 1970s.  He has been referred to as Canada's greatest songwriter and his songs have been recorded by some of the world's most renowned musical artists.  Lightfoot's biographer Nicholas Jennings said, "His name is synonymous with timeless songs about trains and shipwrecks, rivers and highways, lovers and loneliness."

Lightfoot's songs, including "For Lovin' Me", "Early Morning Rain", "Steel Rail Blues", "Ribbon of Darkness" - a number one hit on the U.S. country chart with Marty Robbins's cover in 1965 - and "Black Day in July", about the 1967 Detroit riot, brought him wide recognition in the 1960s.  Canadian chart success with his own recordings began in 1962 with the No. 3 hit "(Remember Me) I'm the One", followed by recognition and charting abroad in the 1970s. He topped the US Hot 100 or Adult Contemporary (AC) chart with the hits "If You Could Read My Mind" (1970), "Sundown" (1974); "Carefree Highway" (1974), "Rainy Day People" (1975), and "The Wreck of the Edmund Fitzgerald" (1976), and had many other hits that appeared in the top 40.

Several of Lightfoot's albums achieved gold and multi-platinum status internationally.  His songs have been recorded by many notable artists.  The Guess Who recorded a song called "Lightfoot" on their 1968 album Wheatfield Soul; the lyrics contain many Lightfoot song titles.

Robbie Robertson of the Band described Lightfoot as "a national treasure".  Bob Dylan, also a Lightfoot fan, called him one of his favourite songwriters and said, "I can't think of any Gordon Lightfoot song I don't like.  Every time I hear a song of his, it's like I wish it would last forever.... ".  Lightfoot was a featured musical performer at the opening ceremonies of the 1988 Winter Olympic Games in Calgary, Alberta and has received numerous honours and awards.
