Representing Ireland are actress Saoirse Ronan, singer Hozier, and golf star Rory McIlroy.
The full list features 300 young innovators and entrepreneurs from across 10 categories, including the arts, industry, and technology.
Randall Lane, editor of Forbes, said: “Researching, vetting and launching our first ever 30 Under 30 Europe list was an incredible task.
“We scoured the continent to find the most talented millennials and, with the help of our expert judges, are proud to honour 300 of the most important young entrepreneurs, creative leaders and brightest stars in Europe right now.”
In the first “30 Under 30 Europe” list, compiled by US magazine Forbes, the United Kingdom dominates the entertainment category.
A dozen of the 30 actors, musicians and sports stars are from the UK.
Brits on the list, which mirrors the long-established US version, include stars of Star Wars: The Force Awakens Daisy Ridley and John Boyega, Game Of Thrones actress Emilia Clarke, Star Wars lead Daisy Ridley, tennis ace Andy Murray, athlete Jessica Ennis-Hill, singers FKA Twigs, Ed Sheeran, Sam Smith and Florence Welch, and rapper Little Simz.
The Forbes list entries were vetted by TV personality Kelly Osbourne, athlete and philanthropist Dame Kelly Holmes, and PR guru Alan Edwards.
Those listed have been recognised for their game-changing leadership, disruption of their field, and likelihood of changing the entertainment industry in the next half century.
