This is a list of foreign players in the Ekstraklasa, which commenced play in 1927. Up to now, 114 different federations associated with one of the following: AFC, CAF, CONCACAF, CONMEBOL, OFC or UEFA have been represented in Ekstraklasa.
Players must meet both of the following two criteria:
More specifically,
Clubs listed are those for which the player has played at least one Ekstraklasa game – and seasons are those in which the player has played at least one Ekstraklasa game. Note that seasons, not calendar years, are used. For example, "1992–95" indicates that the player has played in every season from 1992–93 to 1994–95, but not necessarily every calendar year from 1992 to 1995. Therefore, a player should always have a listing under at least two years – for instance, a player making his debut in 2016, during the 2015–16 season, will have '2015–16' after his name. This follows the general practice in expressing sporting seasons.
In bold: players who have played at least one Ekstraklasa game in the current season (2025–26 season), and are still at a club for which they have played. This does not include current players of an Ekstraklasa club who have not played an Ekstraklasa game in the current season.
Details correct as of 3 September 2025. Please note: This list is currently being reworked, and may still include players who are/were eligible to play for Poland.
