The prisoners, dressed in grey prison uniforms, were greeted by hundreds of Gazans who gathered around the buses as they approached the city's European Hospital.
The prisoners were to undergo medical checks at the hospital before heading to their homes.
"In blood and spirit, we shall redeem you, prisoner!" chanted some in the crowd as the men left the buses one by one.
Some prisoners stuck their heads out of the windows of the vehicles as they tried to spot relatives or talk to people they knew in the crowd.
According to the Palestinian Prisoners' Club in Ramallah, 150 of the 183 detainees released on Saturday as part of the truce between Israel and Hamas were to be transferred to Gaza.
"This is a new day of victory for our people. Today, a new group of our heroes is being released, seeing freedom despite the occupation's will," a Hamas official told AFP.
"Among those who arrived in Khan Younis were 111 detainees arrested by Israel after October 7, 2023, but they have no connection to the Al-Aqsa Flood," the Hamas offensive on October 7, 2023, he said.
The prisoners were released in exchange for three Israeli captives freed earlier on Saturday by Hamas, including two who were handed over to the Red Cross in Khan Younis.
The buses brought the prisoners to the Palestinian territory through the Karm Abu Salem (Kerem Shalom) crossing.
A bus departed Ofer Military Prison earlier on Saturday with some 32 prisoners headed for the West Bank. The Palestinian prisoners were cheered upon their arrival in Ramallah on buses of the International Committee of the Red Cross (ICRC).
According to Palestinian authorities, the 183 prisoners include dozens serving lengthy or life sentences and 111 people from the Gaza Strip who were detained after 7 October 2023 and held without trial.
