Max Murphy has joined Bohemians from Shamrock Rovers, while Jesse Devers and Mark Timlin have signed for Finn Harps ahead of the 2022 SSE Airtricity League season.
Mayo man Devers returns for a second spell at the Ballybofey club, having played a major role in the club's promotion to the Premier Division in 2018.
The winger was part of the Sligo Rovers side who finished fourth in the 2020 season, qualifying for the Europa League.
Devers told club media: "I’m delighted to be back at the club. I haven’t enough good things to say about the people behind the scenes and how I was treated in my first spell here. I’m really excited to get started now in preseason and hopefully we’ll have a good season."
Buncrana man Timlin's return makes him the club's longest serving player, having initially joined on loan from Derry City in 2017 before signing his first deal with the club ahead of the 2018 season.
After a tough couple of years with injury, Timlin is hoping that the worst is behind him, saying: "I’ve been really unlucky over the past couple of years with different injuries. I’ve just been focusing on keeping my head down, getting my body right and hopefully I’m over the worst of it and can hit the ground running in the New Year."

Earlier on Monday, Max Murphy's move from Shamrock Rovers to Bohemians was confirmed.
The defender spent the last three seasons at the Hoops and enjoyed plenty of first-team action in the title-winning season for Stephen Bradley's side.
Elsewhere, St Pat's have named Jon Daly as assistant manager ahead of the new season, working alongside new boss Tim Clancy.
Clancy said: "Jon has a lot of experience in professional football over the last twenty years as both a player and a coach and I'm very happy to welcome him to the club.
"We completed our UEFA A Licence together a few years ago, we have a very good relationship and we’d have similar opinions on football and how the game should be played.
"Jon has worked at a high level in recent years with Hearts at U20 and senior level, and has recently been working in Finland."
