Their female counterparts failed to make the cut in the US poll, but Una Healy of girl band The Saturdays was named the most desirable Irishwoman.
The survey of more than 40,000 singletons by travel dating website MissTravel.com, pinpointed men from Ireland as the second most desirable nationality in the world, but Irish women scored a dismal 24th place in the poll of the world’s sexiest women.
The survey, conducted among more than 30,000 US women and 13,000 US men, named Farrell as the most handsome famous face associated with the country.
He was pipped to the top spot by Prince Harry, who ensured Britain’s place as the sexiest nationality in the world.
Colombian women were in poll position in the survey, with Shakira as their famous face — with Brazilian and American women coming in second and third positions.
“If the list were to be expanded, Irish women would come in at number 24 with the famous face being Una Healy,” said a spokeswoman for the MissTravel website.
The site, which has more than 250,000 members, caused a stir in the US when it launched last year.
The travel dating social network seeks to pair wealthy men seeking travelling companions with women who can’t afford to go on adventures alone.
“Attractive people fly free,” says the site.
One in five of the women surveyed said they go weak at the knees for an Irish accent.
Farrell’s accent coupled with his bad boy reputation made him the second most attractive man in the survey, according to the MissTravel spokeswoman.
“In the States, women not only long for hyper- masculine men, but also for the grace and appeal of a European man.
“The attraction to Irish men is a combination of his character and worldly manner.
“Colin Farrell is the bad boy who knows how to handle any given situation, and still manages to seduce a woman with words.”
