The Muravyov-Amursky Peninsula (Russian: полуостров Муравьёва-Амурского) is a peninsula in Primorsky Krai, Russia, located in Peter the Great Gulf of the Sea of Japan. Vladivostok, the administrative center of Primorsky Krai, is located on the southern tip of the peninsula.


The peninsula is approximately 30 km long and 12 km wide, subdividing Peter the Great Gulf into Amur Bay on its west, and Ussuri Bay on its east. The Eastern Bosphorus separates the peninsula from Russky Island, the northernmost island of the Eugénie Archipelago immediately south of the peninsula. Lazurnaya Bay on the eastern shore of the peninsula contains sand beaches.


Historically the Muravyov-Amursky Peninsula belonged to the region known as Manchuria, ruled by the Jurchen people that became part of the Manchu, who later became the rulers of China in the Qing Dynasty. In the nineteenth century, the region unofficially known as Outer Manchuria was gradually ceded by the Qing to the Russian Empire, with the Treaty of Aigun in 1858 and the Convention of Peking in 1860. Lands ceded by Convention of Peking included the Muravyov-Amursky Peninsula, and were later organized by Russia into Primorsky Krai. The Russians named the peninsula after Count Nikolay Muravyov-Amursky, who had played a major role in Russian expansion from Siberia towards the Pacific Ocean.
