Mansfield have appointed David Flitcroft as their new manager after agreeing compensation to bring him in from Swindon.
Flitcroft, 44, succeeds Steve Evans who left the club on Tuesday to take charge at Peterborough.
The Stags sit fifth in League Two , two points behind third-placed Wycombe with a game in hand, and Flitcroft joins from a club who are also challenging for promotion.
Assistant manager Ben Futcher has also arrived from Swindon to continue working at Flitcroft's number two.
Mansfield chairman John Radford said on the club's website: "We have acted swiftly and diligently in appointing our new manager and are delighted to welcome David Flitcroft to Mansfield Town Football Club."
Speaking at a press conference, Flitcroft said: "When you get a call saying you've been headhunted by a club like Mansfield, I spoke to the chairman and the appreciation I felt was very welcoming.
"When we came here and won earlier in the season, we got applauded off by the Mansfield fans. I felt the warmth from the supporters and really liked it here.
"It's probably the easiest decision when I sat in front of the chairman. Their passion and their drive is evident. You don't often get opportunities where everything is in place and there's a real forward momentum.
"I've got a situation here where I'm coming to a club which is thriving on and off the pitch. There's no need for a lot of change. I'm not coming into a rescue act.
"Our team is in incredible form. Mansfield fans are desperate for it (promotion). Everyone's fighting to get out of this league and that's a pressure, that's why I've come to this football club.
"I wouldn't be sat here [if I couldn't get this club into League One ]. I had a fantastic group of players [at Swindon] and I worked for a fantastic chairman. I must thank Lee Power. I couldn't turn this opportunity down.
"I'm absolutely looking forward to Saturday. We respect every opponent in League Two and we will prepare as if this game will be on against Stevenage."
Swindon, who are three points behind the Stags, said in a statement they were "extremely disappointed at the timing" of Flitcroft's exit and confirmed midfielder Matt Taylor had been put in temporary charge of the first team.
