The 23-year-old is one of ten Brits to earn selection, six men and four women, and comes a matter of days after a successful outing at the national championships last weekend.
Keatings, who represented Team GB at the Beijing 2008 Olympic but not London 2012 with injury hampering his chances, won five titles in Liverpool to stake his claim for a place.
He won the British crowns on the pommel horse, parallel bars and high bar at the Echo Arena and was also the winner of two more in the masters competition.
Keatings became the first British gymnast to win an all-around medal at a World Championships with silver in 2009 while he claimed European gold on the pommel horse in 2010.
Newly crowned British all-around champion and double Olympic bronze medallist Max Whitlock has also earned selection as expected as has Daniel Purvis.
Joining them is Sam Oldham, who like Whitlock and Purvis helped Britain win their first men's gymnastics team medal at an Olympics for a century with bronze at London 2012.
Theo Seager is the fifth British male chosen with the sixth and final place to be given to either Ashley Watson or Reiss Beckford with the decision made prior to departure to Moscow.
British all-around champion Gabby Jupp heads up the quartet of women selected and will make her senior international debut in Russia along with Charlie Fellows.
Ruby Harrold and Beijing Olympian Becky Downie complete the women's quartet and British Gymnastics head of performance sport Tim Jones is relishing the challenge ahead at the Europeans.
"As the first major event of the new Olympic cycle we have taken the opportunity to give experience to a group of new seniors at a major championships," said Jones.
"Clearly we want to maintain the momentum the sport gained from our historic results at the London Olympics but similarly we are aware that in the context of the next four year cycle we are building towards the important results that will come in 2015."
