Prop Cian Healy is expected to miss the start of the 2014 RBS 6 Nations after undergoing surgery on his injured ankle on Wednesday.
The Welsh regions' Cardiff Blues and the Ospreys supply six players apiece. It is the Blues' best total since their forerunners Cardiff had six players named in the original touring party in 1968.
Swansea and Neath combined have never bettered the Ospreys' selection..
Director of Celtic Rugby David Jordan said: "The make-up of the 2009 Lions touring party reflects the standard that the players based in the Magners League have shown over the season and when they have participated in other tournaments.
"Celtic teams already hold three cross-border titles - the RBS 6 Nations trophy and the Heineken and EDF Energy Cups - and it would be an immense achievement if being part of a winning British & Irish Lions touring party could be added to the CV of some of our players.
"On behalf of the Board of Celtic Rugby, I would like to congratulate all those who have been selected and wish them well in their endeavours over the summer."
