The release of 33 people means 150 Palestinians have been released since Friday – the day both sides began swapping hostages and prisoners.
Fifty-one Israeli hostages, including three-year-old-twin sisters, have been freed by Hamas as part of the deal.
Qatar has said the pause in fighting will be extended by two days, which Israel has not confirmed or denied.
Little information has been released about the latest group of Palestinians to be freed.
On Monday both Hamas and Qatar – which has played a major role in the talks between the warring sides – said 30 Palestinian children and three women were due to be freed.
The Israel Prison Service later said 33 people had been freed from Ofer prison in the West Bank, and a detention center in Jerusalem, but did not specify their genders or ages.
By the evening, Reuters news agency reported that a bus carrying the newly released Palestinian prisoners had arrived in Ramallah, in the occupied West Bank.
Images showed people in the Palestinian city, waiting to greet them – some carrying Hamas flags, their faces covered with balaclavas.
Separate images showed a Palestinian boy named Muhammad Abu Al-Humus reuniting with his mother, and other family members, at the family’s home in east Jerusalem.
It was not immediately clear which facility he had been detained in, or for how long.
While fighting between Hamas and Israel is temporarily suspended, aid organizations have taken the opportunity to send lorries into Gaza filled with essentials such as food, water, fuel, and medicines.
Hamas has committed to releasing another 20 women and children, should a two-day extension of the truce go ahead.
Israel has not commented explicitly on the extension, but Prime Minister Benjamin Netanyahu’s office said on Monday evening that it had “approved the inclusion of 50 female prisoners in the list of prisoners eligible to be released if a release of additional Israeli hostages is carried out”.
