List of North American animals extinct in the Holocene

File:Location North America.svg

Map of North America

This is a list of North American animals extinct in the Holocene that covers extinctions from the Holocene epoch, a geologic epoch that began about 11,650 years before present (about 9700 BCE)Template:Efn-ua and continues to the present day.<ref>Template:Cite journal</ref>

Recently extinct animals in the West Indies and Hawaii are in their own respective lists.

Many extinction dates are unknown due to a lack of relevant information.
