USS Nathan Hale (SSBN-623) was the sixth Lafayette class nuclear-powered fleet ballistic missile submarine produced. She was named for Captain Nathan Hale (1755–1776), a Connecticut schoolteacher who served in the Continental Army and known most famously for giving his life as a spy during the American Revolutionary War.

The Lafayette class of submarine was an evolutionary development from the Ethan Allen class of fleet ballistic missile submarine, slightly larger and generally improved. This class, together with the George Washington, Ethan Allen, James Madison, and Benjamin Franklin classes, composed the "41 for Freedom," the Navy's primary contribution to the nuclear deterrent force through the late 1980s. The James Madison and Benjamin Franklin classes are combined with the Lafayettes in some references.
