The Khuriya Muriya Islands (also Kuria Muria, Kooria Mooria, Curia Muria) (Arabic: جزر خوريا موريا; transliterated: Juzur Khurīyā Murīyā or Khūryān Mūryān) are a group of five islands in the Arabian Sea, 40 km (25 mi) off the southeastern coast of Oman.

A group of Liverpool entrepreneurs were granted monopoly rights to harvest the abundant guano deposits, but after having met resistance from the local inhabitants who considered that resource theirs, and questions in the British parliament about the advisability of granting monopoly rights to anyone, the mining was abandoned after some 200,000 tons had been extracted between 1855 and 1860.

Due to their remoteness, the lack of anchorages and the fact that the inhabitants continued to consider themselves subjects of the Sultan of Muscat, the islands remained un-administered and, for decades, were only sporadically visited by British officials.

[5][6] While technically part of Aden Colony, the islands, because of their remoteness and inaccessibly, were left to the supervision of the British Resident in the Persian Gulf.

[9] The island group has been designated an Important Bird Area (IBA) by BirdLife International because it supports seabird breeding colonies of red-billed tropicbirds, tropical shearwaters, masked boobies, Socotra cormorants, sooty gulls, and bridled and greater crested terns.
