The Leigh Leopards (known as just Leigh until the completion of the 1994–95 Rugby Football League season and Leigh Centurions from 1995 to 2022) are an English rugby league club. Leigh began Rugby Football Union competition in 1878, and in 1895 became a founding member of the Rugby Football League (originally the Northern Rugby Football Union) that broke away from the Rugby Football Union.

From that first 1895 season under rugby league rules, through to the end of competition in the 2018 RFL Championship season, Leigh has had 1,469 players, excluding non-playing substitutes, take the field during a competitive first-class match. This includes matches that were subsequently abandoned, expunged or re-played, but excludes friendlies.

These Leigh rugby league players have been allocated a sequential heritage number, in order of their appearance, by the Leigh Leopards. Latham, Michael; Hulme, Mike 1 August 1990).

List In the following table: The individual columns may not reflect the exact type of scoring, due to rule changes over the years, though "Total Points" is correct: The table does account for the points associated with kicking-related scoring (goals), during the first two seasons (1895–96, 1896–97) of Northern Rugby Football Union's existence, when conversions were worth 2-points, penalty goals 3-points and drop goals 4-points. From 1897–98 to 1972-73, all goals earned 2-points, so drop-goals were not always tracked separately from other goals for the purposes of "Drop Goals" column on this list. While the "Début" and "Last Match" dates are accurate, and reflect a player's first and last time with Leigh, a player may have played with another high-level rugby league team before, during or after the period of those two dates. Available (incomplete) information is shown indicating players selected to play on national, international (Other Nationalities, British Empire XIII) or regional teams.
