Local disaster management authorities said rain-related accidents were mainly caused by roof collapse, electrocution and minor road mishaps in various areas of the country.
Abb Takk TV reported that Punjab's provincial capital of Lahore was the worst-hit area where over 40 people were killed and several others injured in separate accidents.
Seventeen people, including three school kids and a three-member family of a British national of Pakistani origin, were killed in other parts of the province.
Rain water inundated several low lying areas in the province, trapping hundreds of people inside their houses.
Air and railway traffic were also disrupted by the heavy downpour.
Torrential rain also killed 15 people, including three soldiers in the Pakistani-controlled Kashmir region, the disaster management authority was quoted by Xinhua as saying.
Eight kids were injured when the roof of a seminary collapsed in the country's capital city Islamabad.
The Met Office said heavy rains and thunderstorms are expected in Punjab and Kashmir during the next 72 hours which may also cause flooding in major rivers.
The country's Prime Minister Nawaz Sharif ordered the National Disaster Management Authority and the Punjab government to ensure immediate rescue and relief activities in the rain-hit areas.
Pakistan army has also extended its services for providing rescue and relief to the affected people.
According to Inter Services Public Relations, troops have been dispatched to the flood-hit areas for relief duties.
