Mike Phelan, 54, took over as caretaker boss in July following the departure of Steve Bruce, who is now in charge of Aston Villa.
Phelan – a former Manchester United assistant boss to Sir Alex Ferguson – became a frontrunner for the permanent position after a strong start to the Premier League season.
The Tigers claimed back-to-back wins in the first two weeks of the campaign, with victories over defending league champions Leicester City and Swansea City.
The team have recorded four defeats and one draw since then, and in that time there was growing uncertainty over Phelan’s position as contract talks were drawn out.
However, it has now been confirmed by the club that Phelan will take the team forward on a permanent basis.
Hull are currently 15th in the league table.
