Arsen Ostrovsky is a leading international human rights lawyer and voice in the pro-Israel community. He serves as CEO of The International Legal Forum (ILF), an Israel-based legal network of over 3,000 lawyers in 30 different countries with the goal of combating terror, antisemitism and the delegitimization of the State of Israel in the international legal arena.

Arsen has spoken before the UN Human Rights Council, in parliaments across Europe, to audiences in North America, as well as regularly addressing the Knesset and other high-level forums and student groups. He is considered an expert on Antisemitism, Israeli – Palestinian conflict, BDS Movement and international law, and frequently writes on these topics, including in Newsweek, where he has been a regular columnist, while also appearing on TV and in the media as an expert commentator.

In 2018, Arsen was awarded the Nefesh B’Nefesh Bonei Zion Prize in ‘Israel Advocacy’, while the Jewish Journal has said "it's his fierceness in defending the Jewish people and the Jewish state, that makes him stand out online and in real life.” Leading Israeli publications Jerusalem Post and NRG have profiled Arsen as one of the leaders in the fight against the BDS Movement, while most recently, he was recognized by JNS as one of the ‘Top 40 Advocates for Israel.’

Arsen was formerly a Research Fellow at the Hudson Institute in New York, where his focus was on Israel, United Nations and International Law, and for many years practiced as a litigation attorney in Australia. He has also served as the Executive Director of The Israeli-Jewish Congress, a member of the International Association of Jewish Lawyers and Jurists, and as a legal advisor for the family of captured Israeli soldier Hadar Goldin.

Arsen holds a number of degrees, including a Bachelor of Laws (with Honours) from the University of Wollongong (Australia).

He is based in Tel Aviv, Israel.
