Frank Xavier Altimari (September 4, 1928 – July 19, 1998) was a judge of several state and federal courts in New York State, including the United States Court of Appeals for the Second Circuit.
Born in Queens, New York, Altimari attended St. Francis College in Brooklyn. He received an L.B. from Brooklyn Law School in 1951.
He worked as a lawyer in private practice in Jamaica, New York from 1951 to 1965. During this period, he also was a law professor at St. Francis College from 1954 to 1963, and served on the school board in Westbury, New York from 1963 to 1965.
Altimari's judicial career began when he was elected to the Nassau County District Court in 1965. After serving on that court for four years, he was elected to the Nassau County Court for a term beginning in 1970 and then as a justice of the New York State Supreme Court (the trial court of New York), on which he served from 1974 to 1982. He also again taught at St. Francis College from 1972 to 1973.
On November 23, 1982, President Ronald Reagan nominated Altimari to a seat on the United States District Court for the Eastern District of New York vacated by Edward R. Neaher. Altimari was confirmed by the United States Senate on December 10, 1982, and received his commission the same day.
