The Myanmar Navy (Burmese: တပ်မတော် (ရေ); Burmese pronunciation: [taʔmədɔ̀ jè]) is the naval branch of the armed forces of Myanmar with 19,000 men and women. The Myanmar Navy currently operates more than 122 vessels. Before 1988, the Myanmar Navy was small and its role in the many counterinsurgency operations was much less conspicuous than those of the army and air force. Yet the navy has always been, and remains, an important factor in Myanmar's security and it was dramatically expanded in recent years to a provide blue water capability and external threat defence role in Myanmar's territorial waters.

The naval arm of the Royal Armed Forces consisted mainly of river-faring war boats. Its primary missions were to control the Irrawaddy, and to protect the ships carrying the army to the front. The major war boats carried up to 30 musketeers and were armed with 6- or 12-pounder cannon. By the mid-18th century, the navy had acquired a few seafaring ships, manned by European and foreign sailors, that were used to transport the troops in Siamese and Arakanese campaigns.

Burma ⁱ/ˈbɜrmə/ BUR-mə, also known as Myanmar ⁱ/ˌmjɑːnˈmɑr/ MYAHN--MAR, is a country in South Asia and Southeast Asia. It is bordered by India, Bangladesh, China, Laos and Thailand. One-third of Burma's total perimeter of 1,930 kilometres (1,200 mi) forms an uninterrupted coastline along the Bay of Bengal and the Andaman Sea. At 676,578 km² (261,227 sq mi), it is the 40th largest country in the world and the second largest country in Southeast Asia. Burma is also the 24th most populous country in the world with over 60.28 million people.

Burma is home to some of the early civilizations of Southeast Asia including the Pyu and the Mon. In the 9th century, the Burmans of the Kingdom of Nanzhao, entered the upper Irrawaddy valley and, following the establishment of the Pagan Empire in the 1050s, the Burmese language and culture slowly became dominant in the country. During this period, Theravada Buddhism gradually became the predominant religion of the country. The Pagan Empire fell due to the Mongol invasions (1277–1301), and several warring states emerged. In the second half of the 16th century, the country was reunified by the Taungoo Dynasty which for a brief period was the largest empire in the history of Southeast Asia. The early 19th century Konbaung Dynasty ruled over an area that included modern Burma as well as Manipur and Assam. The country was colonized by Britain following three Anglo-Burmese Wars (1824–1885).
