Connacht's top try scorer Alex Wootton has joined the westerners on a permanent basis after impressing on loan from Munster.
The winger moved to the Sportsgrounds last summer and is currently the PRO14's joint top try scorer.
Wooton is one of 21 of Andy Friend's players to sign on the dotted line for next term, with Ireland internationals Jack Carty, Ultan Dillane, Dave Heffernan and Finlay Bealham among that number.
Bundee Aki had already signed a new deal late last year.
“I am delighted to see so many of our current crop of players sign on for another season," said Friend, after his side were pipped for a place in the PRO14 final by Munster in Conference B but still have the Challenge Cup knock-out stages to prepare for.
"This is still a very challenging time for everyone in Irish Rugby so to have them commit to Connacht Rugby again says it all about the belief we have as a group to continue the progress we’re making.
"Seventeen of the 21 players were once part of the Connacht Academy, and in that group we have a mix of established Irish internationals, experienced players within the province and plenty of young players still in the early stages of their careers.
"I have been very impressed by Cian Prendergast and Oran McNulty, and their first Professional contracts is the culmination of years of work from grassroots level to where they are now.
"Congratulations not just to them but their parents, coaches and all the other volunteers who helped them along the way.
"We are continuing to shape the squad for next season, with further discussions ongoing, and supporters should expect more positive news in the weeks and months ahead.”
