Giacchino Michael "Jack" Ciattarelli (/ɪtəˈrɛli/ chi-tə-RELL-ee; born December 12, 1961) is an American politician and businessman. A member of the Republican Party, he served in the New Jersey General Assembly from 2011 to 2018, representing the 16th legislative district.

Ciattarelli was the Republican nominee for New Jersey governor in the 2021 gubernatorial election, losing to Democratic incumbent Phil Murphy in a race that was much closer than expected. He is once again the Republican nominee in the 2025 election.
