Charles Oliver Iselin (June 8, 1854 – January 1, 1932) was an American banker and yachtsman who was captain of racing yachts that won the America's Cup three times.

His great-great-grandfather Isaac Iselin-Roulet came to America in 1801 from Basel, Switzerland,[2] where the Iselin's had been merchants, public officials, and military and professional men since the 14th century.

[3] Oliver was considered to be one of the greatest American yachtsmen of his time, participating in and winning six consecutive America's Cup races: 1887, 1893, 1895, 1899, 1901 and 1903.

[4] He built a large breakwater next to his Premium Point, New Rochelle estate All View so that he could dock his yachts Defender, Reliance and Columbia safely at home.

[7][8] After her death, he married Hope Goddard (1868–1970), who was the first woman ever to serve as part of the crew on an America's Cup yacht, in 1894.
