Uri Lupolianski, born in 1957 in Jerusalem, is an Israeli Haredi leader and politician. He is best known for founding Yad Sarah in 1980, a major volunteer organization providing free medical equipment loans and ambulance services across Israel, which he served as president until 2003, growing it into one of the country's largest nonprofits with high public recognition. Prior to politics, he was active in Jerusalem's Haredi community organizations. Elected Mayor of Jerusalem in 2003 under the United Torah Judaism banner, he served until 2008, prioritizing infrastructure projects, welfare services, and Haredi community needs, though his tenure faced criticism for alleged favoritism and fiscal issues; he lost re-election to Nir Barkat. Subsequently, he served as a Member of the Knesset (MK) for United Torah Judaism from 2009 to 2013. In 2013, he was convicted of bribery and breach of trust for accepting improper gifts from a contractor during his mayoral term, receiving a six-month community service sentence and resigning from the Knesset. Post-conviction, Lupolianski has maintained a lower public profile but remains influential in Haredi circles in Jerusalem, involved in various communal leadership roles reflecting his long-standing commitment to ultra-Orthodox welfare and advocacy.
