Frank Joseph Guarini (1924) is a politician of the American Democratic Party, Congressman of the State of New Jersey in the United States House of Representatives for seven terms from 1979 to 1993 and President of the National Italian American Foundation (NIAF). He received the Magna Grecia International Award in 2002, during the sixth edition of the Magna Grecia Week held in New York, an initiative promoted by the Foundation bearing the same name and chaired by President Nino Foti.

Guarini was born in New Jersey to a family of Italian origin, the son of Frank J. Guarini Sr. and his mother Caroline Loretta Critelli from Molise.

After serving in the U.S. Navy aboard the USS Mount McKinley, flagship of the Pacific Amphibious Fleet, until 1946, he received the Navy Commendation Medal and three Battle Medals.

On his return, he graduated from the New York University School of Law in 1950, and then continued his research work at the Hague Academy of International Law in The Hague.

In 1951 he was admitted to the New Jersey Bar Association, New York, and began his internship first in the Supreme Court of the United States, then in the Court of International Trade, the Treasury Department, the Court of Appeals and the Tax Court, acquiring considerable experience in trade matters. In this regard, he worked on the modernization of the laws concerning trade tariffs and duties, a commitment recognized by the U.S. Court of International Trade with the annual award for "outstanding contribution to the administration of justice in international trade law".

Guarini has also been particularly active on civic issues and education. In 1988, with the appointment of president and board member of NIAF, he put highest priority on the Italian American community by supporting the study of the Italian language and culture. Working tirelessly to support heritage preservation through the study of Italian, he introduced a number of educational programs, including the "Teacher of the Year" award in Italian and the "Italian Culture and Language Fellowships," a partnership with the Washington Post and the Italian Embassy. He has taught in teacher formation seminars at Harvard University and Lago del Bosco, the first campus of Italian language and culture in the United States, as well as having placed greater emphasis on Italian in the Foundation's scholarships and awards:

"Language opens the door to its culture. It gives rise to art, music, literature, science, fashion and architecture. With it, we are able to explore important business, government, and trade opportunities, as language enriches every aspect of life. Therefore, the study of the Italian language will be preserved in the next generation."

Throughout his life and career, Guarini has always maintained a strong interest in education. He founded centers and institutes at Dartmouth College, New York University School of Law, St. Peter's University, New Jersey City University, and John Cabot University (JCU). Since joining the latter's board of trustees in 1995, Guarini has shown unwavering support for the University. Thanks to his generous donation, the "Frank J. Guarini School of Business" was founded.

He also received the America Award from the Italy-USA Foundation in 2014 and the city of Dartmouth founded the "Frank Guarini Institute for International Education" in recognition of its long-standing support of the College.
