A coalition of New York City's most prominent Jewish organizations has announced a rally against antisemitism set for Dag Hammarskjöld Plaza, directly across from United Nations Headquarters in Midtown Manhattan, on September 23. The demonstration lands the day before Israeli Prime Minister Benjamin Netanyahu is scheduled to address the General Assembly, and organizers say it is meant to call on world leaders to act decisively against what they describe as concerns about antisemitism.
The rally was organized by a wide coalition that includes the Jewish Community Relations Council of New York, the Conference of Presidents, the Anti-Defamation League, the American Jewish Committee, UJA-Federation of New York, StandWithUs, the Israeli American Council, the Union for Reform Judaism, the United Synagogue of Conservative Judaism, and Yeshiva University, according to The Times of Israel. The lineup reflects broad communal participation in the rally and ongoing concern about antisemitism.
Timing Tied to the UN's Biggest Week
The gathering is scheduled during the UN General Assembly's high-level week, a stretch that draws heads of state to Turtle Bay, per the United Nations. The rally's date places it directly ahead of Netanyahu's own remarks to the body. JNS identified Dag Hammarskjöld Plaza in Manhattan as the site of a July 7, 2026 protest against Israeli National Security Minister Itamar Ben-Gvir, according to JNS.
The rally follows separate scenes of tension elsewhere in the city just a day earlier. Pro-Israel activist groups EndJewHatred and the Lawfare Project protested near the Manhattan offices of the Democratic Socialists of America on September 9, drawing several hundred attendees, per the Times of Israel report. Protesters at that demonstration demanded that Mayor Zohran Mamdani and New York City Schools Chancellor Kamar Samuels implement a mandatory curriculum on the September 11, 2001 terror attacks.
A City Hall Backdrop of Friction
The UN rally comes against a backdrop of strained relations between segments of the Jewish community and City Hall. Mamdani has previously denounced Netanyahu as a war criminal, though city attorneys advised him after his inauguration that New York City lacks the legal authority or jurisdiction to execute International Criminal Court arrest warrants against foreign dignitaries, as reported by Hoodline. Israel's Ambassador to the United Nations, Danny Danon, publicly criticized Mamdani's arrest threats in July 2026, calling them legally baseless political theater that inflames local tensions.
Mamdani has also weighed in on a separate controversy: he called comments from Hasan Piker, who said in 2019 that America deserved 9/11, objectionable and reprehensible, per the Times of Israel's live update. The mayor has said he will attend the September 11 memorial. The Justice Department's Civil Rights Division has separately opened an inquiry into antisemitic crimes in New York City, according to the Combat Antisemitism Movement.
Hate Crime Numbers Driving the Urgency
The rally's timing reflects concerns about hate crimes in the city.
The trend is not confined to this year. The Anti-Defamation League's annual audit, released in May, found that physical assaults against Jewish individuals nationwide reached their highest level since record-keeping began in 1979, with Axios reporting high totals for New York and New York City, Axios reported. The article also places those findings in the context of related concerns in recent weeks.
State and National Responses Ahead of the Holidays
New York Governor Kathy Hochul announced on September 8 a record $70 million state grant distribution to bolster security at non-profit institutions, synagogues, and K-12 schools ahead of the Jewish High Holidays, according to the New York Governor's Office. A Jewish Students' Bill of Rights statement was issued on September 9, according to the Jewish Federations of North America.
Antisemitism has also featured in discussion of the city's hate-crime response. The issue has been discussed alongside NYPD reports on hate crimes. For organizers of the September 23 rally, the plaza across from the UN represents both a demand aimed at visiting world leaders and a pointed message to City Hall about the safety of New York's Jewish residents.
