The former Australia batter helped the squad in the United Arab Emirates, as they reached the semi-finals, and will assist the squad during the 2022 tournament
Pakistan will again have Matthew Hayden on hand as a team mentor for the men's T20 World Cup.
The 50-year-old worked with the squad during the 2021 tournament in the United Arab Emirates in an identical role, as the team reached the semi-finals.
They were knocked out by eventual champions Australia, who host the 2022 tournament, in a dramatic semi-final in Dubai.
"I am extremely excited to be reuniting with the Pakistan team as their mentor for the ICC Men's T20 World Cup in Australia and can't wait to join the culture again and feel the spirit of One Nation One Passion," said the two-time 50-over World Cup winner
"I think this Pakistan side has got what it takes to excel in Australia and the conditions will really suit them, both from a batting and bowling perspective.
"This team has all of its bases covered and I am sure it will light up the World Cup as it did in the UAE last year.
"I feel privileged to be given an opportunity to pass on all my experience and knowledge about all conditions in Australia and can’t wait to be back in the Pakistan dressing room."

By all accounts, Hayden threw himself into the role last year, channelling the memory of Dean Jones who devoted himself to cricket in Australia and Pakistan. The former left-hander also read the Quaran with Mohammad Rizwan.
Having spent much of his 18-year professional career playing first-class, one-day or T20 cricket in his Aussie homeland, Hayden will add significant experience to a Pakistan side that sit second in the men's ICC T20I rankings.
PCB chair Ramiz Raja said: "He is a proven performer with his credentials acknowledged and recognised world-over.
"He brings with him a wealth of knowledge about Australia conditions and I am confident his involvement will significantly benefit our extremely talented cricketers for the World Cup and future tours Down Under."
Hayden will link up with Pakistan upon their arrival in Brisbane on October 15, following the tri-series in Christchurch against New Zealand and Bangladesh. They are scheduled to start their campaign against India at the MCG on October 23.
Babar Azam's side are currently competing in the Asia Cup in the UAE and face Sri Lanka in the final on Sunday (September 11). They face the same opponent in the last match of the group stage on Friday (September 9).
