The Qatari Emiri Navy (Arabic: البحرية الأميري القطرية, romanized: Al-Bahriyah Al-Amiriyah Al-Qatariyah) (QEN), is the naval branch of the armed forces of the State of Qatar.

The State of Qatar did not possess any ships originally upon gaining independence from the United Kingdom in 1971, but by 1992 the country's armed forces had grown considerably, and included a navy of about 700 personnel.

[3] Unable to support a large military, Qatar relies on a smaller mobile force that can quickly repel incursions into its territorial waters.

Despite the expansion, the Qatar Emiri Navy remains too under-manned, under-trained, and under-equipped to be able to effectively defend its waters as well as the commercial assets in it.

[20] In February 2020, Qatar had a memorandum of understanding (MoU) with Italian defense company Fincantieri, to acquire submarines and aircraft carriers,[21] based on a 5-billion-euro deal signed in 2017.
