Michael Ben-Ari (Hebrew: מיכאל בן ארי, born 12 October 1963) is an Israeli politician, and former member of the Knesset. During the 18th Knesset, Ben Ari was a member of the National Union party, until it broke up as elections for the 19th Knesset approached and he co-established the Otzma LeYisrael party. He failed to be re-elected to the 19th Knesset. He was the first outspoken disciple of Rabbi Meir Kahane to have been elected to the Knesset. He has a Ph.D in Land of Israel and Archaeology studies.
Ben-Ari grew up in the Kfar Shalem neighbourhood in south Tel Aviv, born to Mizrahi Jewish parents from Iran and Afghanistan. He studied at the Bnei Akiva yeshiva at Kfar Haroeh, at the hesder yeshiva in Yamit, and at the Mercaz HaRav yeshiva. As part of his hesder army service, he was with the Nahal settlement at Neve Dekalim from 1982 to 1986. He studied education at Bar-Ilan University, gaining a BA, before studying the Talmud for a Master's degree, and the Land of Israel for a PhD. He was a rabbi teacher at the Darchei No'am Yeshiva in Petach Tikva as well as the Bnei Akiva Yeshiva in Giv'at Shmuel.
Previously a member of the banned Kach party, Ben-Ari still views himself as Meir Kahane's follower. He ran with the Herut - The National Movement party in the 2003 elections, and for the 2006 elections, he ran with the Jewish National Front party, but both times failed to be elected since the parties did not pass the threshold. Leading up to the 2009 elections, the Jewish National Front joined a new party called Eretz Yisrael Shelanu. That new alliance then joined the National Union, and Ben-Ari was placed fourth on the combined list for the elections. He entered the Knesset as the party won four seats. Once elected, he appointed Hebron residents and Kahanists Baruch Marzel and Itamar Ben-Gvir as his aides in the Knesset.
Unlike his teacher, Rabbi Meir Kahane, who was marginalized and isolated as a member of Knesset, Ben Ari has succeeded in integrating himself into Israel's political arena. According to Uri Avnery his extremist perorations are listened to with 'rapt attention' by most factions in the Knesset.
Ben Ari opened his external Member of Knesset office in the south Tel Aviv neighborhood in which he grew up. Throughout the 18th Knesset session, he struggled to bring attention to the growing number of Sudanese whom he blamed for increasing crime rates and causing other problems for local residents. In June 2011, to draw attention to what he saw as the growing illegal alien problem, he bused 40 Sudanese nationals to a prestigious pool in northern Tel Aviv, provided them with new bathing suits and paid for their entrance.
Ben-Ari's 2012 visa application to attend a conference in D.C. was denied on the State Department's "prerogative to ban terrorists from entering the country." 
In July 2012, all Members of Knesset were sent a copy of the New Testament by a missionary organization. Ben Ari called it provocative, and subsequently tore his copy, referring to it as a despicable book responsible for the murder of millions of Jews, and which should, including the senders, be put in "history's trash can". 
In November 2012 Ben-Ari and Aryeh Eldad left the National Union to establish Otzma LeYisrael. Ben-Ari and Eldad publicly burned Palestinian flags in response to the passage of United Nations General Assembly resolution 67/19.  The party failed to cross the 2% threshold in the 2013 elections and Eldad subsequently lost his Knesset seat.
On 1 June 2009, Ben-Ari was handcuffed and arrested after being involved in an incident near Yitzhar in the West Bank, and despite his parliamentary immunity as Member of Knesset. He climbed onto an army truck and refused to get off, demanding that the Israel Border Police and Israel Defense Forces soldiers explain to him why they had arrested and handcuffed minors at a roadblocking protest. Knesset speaker Reuven Rivlin called the police commissioner and clarified that the police has no authority to arrest an MK without his approval. Yitzhak Aharonovich, the Internal Security Minister, justified the arrest, despite Ben Ari's parliamentary immunity, saying that he will not let MKs violate the law. Ben-Ari's response was to suggest that Aharonovich first verify the facts before coming to conclusions. The IDF Spokesman’s office started an investigation into whether the IDF and Border Guard acted illegally in their treatment of Ben-Ari. On 16 June, the Knesset Committee discussed Ben-Ari's arrest. While the semantics of the word 'arrest' were discussed, it was confirmed that Ben-Ari was not incarcerated. It was reported that a letter from the Chief of General Staff's office stated that the IDF expects elected officials and public representatives not to fan the flames and to abide by instructions from the security forces. Chairman of the committee, Ze'ev Elkin from Likud, criticized the Ministry of Defense for boycotting the meeting and not sending representatives.
