Bastien Héry joined the club from Limerick at the start of the season, while Ismahil Akinade joined from Bohemians.
Midfielder Héry, who has made 17 league appearances for the club this season, says agreeing to stay for another season was an easy decision.
"Since I've come to the club, I have really enjoyed my football," Héry said. "Everything is set up and ready to go for the club to move forward and I want nothing more than to be part of that.
"There is a great team of people, both staff and players, here. I am happy to stay and keep working for this club."
Striker Akinade has made 18 league appearance for the Blues this season since his move from Bohemians and says he's honoured to remain at the club.
"I'm happy to be back at the club for next season because it's only going one place and that's the top. It was a new challenge to me coming here having left Dublin but I must say I've enjoyed every minute here.
"The dressing room, the fans, the facilities…all brilliant. I'm really looking forward to the future and honoured to be part of it moving forward."
