The 41-year-old, who represented his country for 12 years, has featured on two Lions tours, taking part in the 1997 series win over South
Africa and in the unsuccessful visit to Australia in 2001.
Jenkins served as a specialist kicking coach in the 2009 tour of South Africa and will now join up with the squad once more as they attempt to win their first series in Australia since 1989.
Jenkins said: "It is a great honour to once again be part of a British and Irish Lions tour. I am delighted and grateful to have been offered this opportunity to join the 2013 coaching staff.
"As a player I was lucky enough to tour Australia with the Lions in 2001, it is a great country and they are one of the top teams in world rugby.
"I have clear ideas of what I would like to contribute and I cannot wait to get out onto the training pitch and get started."
Jenkins scored over 1000 points in his international career and still holds the Lions' record for most points by virtue of the 41 he scored in that win in South Africa. The Lions have not won a series since 1997 and head coach Warren Gatland is hoping Jenkins' experience will be beneficial to their cause.
"Neil was one of the foremost kickers in the game. He has been working in the coaching environment in this crucial area with great success in recent years with Wales.
"Tactical kicking, when to kick, how to kick, and of course converting points through penalties and conversions is crucial to on-field success. Neil brings extensive knowledge to the squad in this area and the players can only benefit from this."
