Shelikhov Gulf (Russian: залив Шелихова) is a large gulf off the northwestern coast of Kamchatka, Russia. The gulf is named after Russian explorer Grigory Shelikhov.
It is located in the northeastern corner of the Sea of Okhotsk and branches into two main arms, Gizhigin Bay to the west and Penzhina Bay to the east. Its southwest corner is formed by the P'yagin Peninsula, Yam Bay, and the Yamsky Islands.
The Sea of Okhotsk is a marginal sea of the northwestern Pacific Ocean.

Its northeast corner is the Shelikhov Gulf. The sea is named for the port of Okhotsk, itself named for the Okhota River.
