After talks today, Monk has signed a three-and-a-half year contract.
Assistant Manager Clotet, First Team Coach Beattie and Goalkeeper Coach Flahavan have also agreed contracts until the summer of 2021.
The Club is delighted to have secured the services of one of the game's brightest young managers in Monk, 38.
He began his managerial career when Swansea City Club Captain, in February 2014, succeeding Michael Laudrup.
Having kept Swans in the Premier League, he guided them to a club-best eighth in the 2014-15 campaign.
In the summer of 2016 Monk joined Leeds United and brought the good times back to Elland Road following several mid-table finishes.
In June 2017, Monk took up the reins at newly-relegated Middlesbrough and his time at the Riverside came to an end in December, following an away victory over Sheffield Wednesday with the team sitting three points outside the Play-Offs.
As a player, centre-half Monk made 339 career appearances and lifted the League Cup with Swansea in 2013. He also captained Swans to the League One title and Championship Play-Off Final victory.
He began his career as a trainee at Torquay United before moving to Southampton. It was at Swansea, where he moved in 2004, that he really carved out a niche.
