Leonardo Jardim has signed an extension to his contract with Monaco through to 2019, the principality club announced on Tuesday.
The 40-year-old Portuguese arrived last summer from Sporting Lisbon on an initial two-year deal, but has been rewarded for a largely successful debut campaign at the Stade Louis II.
"It is a sign of confidence from the club, the board, to sign this extension," Jardim told Monaco's official website.
"We have worked hard this season to put in place a new project and I am convinced that the best is to come.
"There are a lot of quality youngsters in this team, we need to build on what we have shown this season. The club is ambitious and so am I."
Monaco vice-president Vadim Vasilyev added: "It is an important step for our club because we wish to build over the long-term with Leonardo Jardim.
"With his staff, he has done a remarkable job this season, obtaining very good results in Ligue 1 and in the Champions League."
Monaco reached the quarter-finals of the Champions League before losing 1-0 on aggregate to Juventus, and are currently third in Ligue 1 with two matches remaining, on course to return to Europe's elite club competition next season.
