This article lists all rugby league footballers who have played first-grade for the Newcastle Knights in the National Rugby League.

Notes: Debut: Players are listed in the order of their debut game with the club. Players that debuted in the same game are added alphabetically, however there are exceptions at times, such as Tom Cant being a late inclusion into his debut game, after Dylan Lucas and Ryan Rivett were already confirmed to be debuting and having their numbers assigned already. Appearances: Newcastle Knights games only, not a total of their career games. For example, Jeremy Smith has played a career total of 214 first-grade games but of those, 75 were at Newcastle. Previous Club: refers to the previous first-grade rugby league club (NRL or Super League) the player played at and does not refer to any junior club, Rugby Union club or a rugby league club he was signed to but never played at. Current players are indicated in bold text for their Knights career years. The statistics in this table are correct as of Finals Week 3 of the 2026 NRL season.
