Per Tomas Cristian Härdin (born 5 October 1967) is a Swedish professional golfer, who was the first Scandinavian player to win The Amateur Championship and to play in the Masters Tournament.

Härdin grew up in Gävle, in the Gästrikland province, part of Norrland, the northern half av Sweden.

[5] Härdin was a member of the Swedish team, along with Håkan Eriksson, Magnus Grankvist, Fredrik Lindgren, Jesper Parnevik and Johan Ryström, finishing bronze medalists at the 1984 European Youth's Team Championship at Hermitage Golf Club, Ireland.

[8][9] Härdin's British Amateur win earned him an invitation to The 117th Open Championship at Royal Lytham & St. Annes Golf Club, England the same year.

However, staying in the northern part of Sweden during the winter, having not played a tournament round since the Eisenhower Trophy in September 1988, Härdin was not able to be competitive at his first visit to Augusta National.

[14][15] After his playing career, he became head professional at Barsebäck Golf & Country Club in Löddeköpinge, Scania province, in southern Sweden.
