The US says it will deny or revoke visas for Palestinian officials wishing to travel to New York next month to attend the UN General Assembly session.
Secretary of State Marco Rubio blamed them for undermining peace efforts and for seeking "the unilateral recognition of a conjectural Palestinian state".
The decision is unusual as the US is expected to facilitate travel for officials of all countries wishing to visit the UN headquarters.
The ban comes as France spearheads international efforts to recognise a state of Palestine at the General Assembly session.
Donald Trump's administration has fully backed Israel in voicing opposition to such a move.
Israel's Prime Minister Benjamin Netanyahu has constantly rejected the idea of a two-state solution - the long-time international formula to resolve the decades-old Israel-Palestinian conflict. It envisages an independent Palestinian state being created alongside Israel in the West Bank and Gaza Strip, with East Jerusalem as its capital.
Netanyahu says recognition of a Palestinian state would amount to rewarding "Hamas's monstrous terrorism".
The Israeli military launched a campaign in Gaza in response to the Hamas-led attack on southern Israel on 7 October 2023, in which about 1,200 people were killed and 251 others were taken hostage.
More than 63,000 people have been killed in Gaza since then, according to the Hamas-run health ministry.
