Willie Reid was a British association football player and coach who was born in Glasgow on 3 May 1884.

Reid spent his life in Scotland, having been born in Glasgow and dying in the nearby district of Baillieston on 1 May 1966, just two days short of his eighty-second birthday. A citizen of the United Kingdom, he lived through a period that saw dramatic changes in the game of football, from its relatively early organised form in the late Victorian era through to the mid-twentieth century. He used English as his working language throughout his career, consistent with his Scottish upbringing and the wider British football culture of the time.

His involvement in the sport spanned two distinct roles: that of a player and, later, that of a coach. This progression from playing to coaching was a path followed by many footballers of his generation, and it meant that Reid remained connected to association football across much of his adult life. The dual nature of his football career — first competing on the pitch and then guiding others from the sideline — reflects the shape of a life dedicated to the game at a grassroots and professional level. Reid's career as both a player and a coach in association football defines the central thread of what is known about his life.
