Cornelius Vanderbilt II (November 11, 1843 – September 12, 1899) was an American socialite, businessman, and a member of the prominent United States Vanderbilt family.
He was the favorite grandson of Commodore Cornelius Vanderbilt, who bequeathed him $5 million, and the eldest son of William Henry "Billy" Vanderbilt (who bequeathed him about $70 million) and Maria Louisa Kissam.
In his turn he succeeded them as head of the New York Central and related railroad lines in 1885.
