The US administration is sanctioning Francesca Albanese, the UN Human Rights Council special rapporteur and a vocal critic of Israel's war on Gaza.
Marco Rubio announced the decision, accusing Ms Albanese of leading a "campaign of political and economic warfare" against the US and Israel.
Ms Albanese, who has described Israeli actions as "genocide," dismissed the sanctions as "mafia style intimidation techniques" and affirmed her commitment to holding states accountable.
This move follows an unsuccessful US campaign to remove her from her post and is viewed by experts as the latest effort to punish critics of Israel's war.
The Trump administration had previously withdrawn the US from the UN Human Rights Council and has been actively working to quell criticism of Israel's handling of the conflict.
