The Neskynpil'gyn Lagoon (Russian: Лагуна Нэскэнпильгын) is a shallow coastal lake in the Chukchi Sea at the northern shore of the Chukotka Peninsula, Russia.

The Neskynpil'gyn Lagoon is separated from the sea by a narrow landspit which completely encloses the lagoon, isolating it from the Chukchi Sea, except for a narrow pass.

The Chukchi village of Neshkan is located in the spit itself, on the eastern side of the pass.

Administratively the whole area around the lagoon belongs to the Chukotka Autonomous Okrug of the Russian Federation.
