Kenny Jackett will remain in charge at Portsmouth until June 2021 after the League 1 side announced that they had extended his contract by two years.
The former Wolves and Millwall manager has been at the helm since June after replacing Paul Cook on an initial two-year deal.
“We’ve been really impressed with the experience, knowledge, hard work and commitment Kenny Jackett brings to Pompey,” chairman Michael Eisner said.
Jackett said: “Pompey is a really special, incredible football club. The Chairman, Board and CEO all share a long-term vision of where the club is going and I want to be a part of that.
“When offered the opportunity to extend my contract it was a very simple decision to make and I am extremely excited about the future of PFC.”
Portsmouth, who are on a three-match unbeaten run in all competitions, travel to Peterborough on Tuesday evening.
