List of Major League Baseball players (K)

This is a listing of Major League Baseball (MLB) players whose last names begin with the letter K. The list includes players who have appeared in at least one MLB game since the inception of the National Association in 1871.

This list is intended to be comprehensive but may not be exhaustive due to incomplete or conflicting records, particularly from the early years of professional baseball. Information regarding player statistics, positions, and years played can be found on official MLB websites and baseball reference sites.

Entries are typically ordered alphabetically by the player's last name, and then by first name if necessary. Nicknames are generally not included unless they are the primary way the player is known. For players with common last names, additional disambiguation may be included, such as years played or primary position.

This resource is maintained and updated periodically to reflect changes in MLB rosters and historical corrections.
