Frank Arthur Vanderlip Sr. (November 17, 1864 – June 30, 1937) was an American banker and journalist. He was president of the National City Bank of New York (now Citibank) from 1909 to 1919, and Assistant Secretary of the Treasury from 1897 to 1901. Vanderlip is known for his part in founding the Federal Reserve System and for founding the first Montessori school in the United States, the Scarborough School and the group of communities in Palos Verdes, California.

Born in rural Illinois, Vanderlip worked in farms and factories until beginning a career in journalism in 1885. His efforts in financial journalism led him to become Assistant Secretary of the Treasury until the National City Bank hired him. While president of the bank, Vanderlip worked with the Jekyll Island group to develop a federal reserve; Vanderlip's later proposals also influenced the creation of the Federal Reserve System in 1913. His later life was focused towards developing Palos Verdes and creating the Scarborough School at his estate, Beechwood, in Briarcliff Manor, New York, as well as gentrifying the hamlet of Sparta, Ossining nearby. In addition, he helped found and was the first president of Sleepy Hollow Country Club. Vanderlip died in 1937 in New York Hospital, after weeks of treatment there.
