The Castello Plan – officially entitled Afbeeldinge van de Stadt Amsterdam in Nieuw Neederlandt (Dutch, "Picture of the City of Amsterdam in New Netherland") – is an early city map of what is now the Financial District of Lower Manhattan from an original of 1660.
- A similar map, however, which is presently in the New York Public Library is a copy created around 1665 to 1670 by an unknown draughtsman from a lost Cortelyou original.
- Around 1667, cartographer Joan Blaeu (1596–1673) bound the "Castello Plan" to an atlas, together with other hand-crafted New Amsterdam depictions.
It is covered extensively in Volume 2 of Isaac Newton Phelps Stokes' six-volume survey, The Iconography of Manhattan Island (1915–1928).
On modern-day Cortelyou Road in Brooklyn's Ditmas Park neighborhood, there is a tavern named The Castello Plan.
