Jacob Weinberger (1882 - May 20, 1974) was a United States federal judge.
Born in Czechoslovakia, Weinberger's family emigrated to Denver, Colorado in the late 1880s, where he attended the public schools. Weinberger received an LL.B. from the University of Colorado School of Law in 1904, and was in private practice in Denver in 1904, and in Gila County, Arizona from 1905 to 1911. He was an assistant district attorney of Gila County from 1907 to 1909. He was a Delegate to Arizona constitutional convention from Gila County in 1910. He was in private practice in San Diego, California from 1911 to 1941, serving as city attorney of San Diego from 1941 to 1943. He was a judge on the Superior Court of San Diego County from 1943 to 1945, returning to private practice until 1946.
On January 24, 1946, Weinberger was nominated by President Harry S. Truman to a seat on the United States District Court for the Southern District of California vacated by Harry A. Hollzer. Weinberger was confirmed by the United States Senate on February 15, 1946, and received his commission on February 21, 1946. Weinberger was initially assigned to a duty station Los Angeles, but on November 1, 1949, he was assigned as the first resident federal judge in San Diego. He assumed senior status on November 1, 1958, serving thereafter until his death, in San Diego, California. Weinberger also served on the Board of Education for the San Diego School District for 21 years. The Jacob Weinberger Elementary School was named for him in 1963, and the Jacob Weinberger U.S. Courthouse in San Diego was renamed in his honor in 1988.
