It won't mean an end to his involvement in the game at the highest level, however, because he recently accepted an offer from Springbok coach Peter de Villiers to become the national side's kicking consultant.
Montgomery played four times against the Lions in 1997, winning the first of his 102 caps in the second Test defeat. He played in the winning third Test and also appeared for Western Province and the Emerging Springboks against the tourists.
There was the prospect of him facing the Lions for Vodacom Western Province 12 years on, but he has now ruled that out by retiring from playing.
Confirming his retirement on SA Rugby he said: "I always planned to retire after this year's Super 14. After my retirement from international rugby, I made myself available for the Stormers this season in the knowledge that I would play a back-up role.
"I am now looking forward to working as kicking consultant to the Boks, but this is the end for me as a player. I was given many opportunities to fulfill my dreams and ambitions and there are many people that inspired me along the way.
"They are too many to mention but I wish to thank them all for putting their faith in me.
Rugby has been very good to me and now is my time to give back to the game."
His 13 year career saw him play more than 300 first-class games. He won the Rugby World Cup in 2007, two Tri-Nations titles and the Currie Cup with Western Province.
He also set every goalkicking record in South African rugby..
