Killip joined Pools in 2019 and has become their number one choice stopper, playing over 100 times for the club, keeping 38 clean-sheets.
The 26-year-old also played an integral role in Hartlepool’s Papa John’s Trophy campaign this season with his save against Charlton Athletic in the quarter-finals helping them to progress to the semi-finals.
Speaking about extending his contract with the club, Killip said: “Delighted to be staying with Hartlepool for another year.
“I’ve really enjoyed my time in the North East and the support from the fans has been first class. We’ve had a strong season back in the EFL and we have given ourselves a good platform to really push on now and I’m excited to be a part of it.”
Killip joins David Ferguson and Tom Crawford in committing their future to the club.
