In Norse myth Rán (often anglicized as Ran) is depicted as a sea deity who captures those lost at sea. She is traditionally portrayed with a net used to seize sailors and is linked with the perils of ocean travel. Rán appears in several Old Norse poems and later retellings where she embodies sea-danger and the fate of drowned mariners.

The film Ran (1985), directed by Akira Kurosawa, is an acclaimed historical drama that adapts themes from Shakespeare's King Lear and classical Japanese history. It is noted for its striking visuals, use of color and large-scale staging. Ran remains one of Kurosawa's best-known late works and is often discussed in studies of world cinema.

In molecular and cell biology, RAN (Ras-related nuclear protein) names a small GTP-binding protein of the Ras superfamily. RAN plays central roles in the transport of proteins and RNA across the nuclear envelope, in mitotic spindle assembly and in regulating the cell cycle. Because of these functions, RAN is frequently mentioned in research on cell division and nuclear transport mechanisms.

In telecommunications, RAN stands for Radio Access Network. The RAN comprises radio base stations and associated equipment that link mobile devices to a mobile operator's core network. Variants such as 3G RAN, E-UTRAN (for LTE) and 5G RAN describe the technology and protocols used in successive generations of mobile networks.

RAN also serves as an abbreviation for the Royal Australian Navy, the sea service branch of Australia's armed forces. Separately, "Ran" is a personal name in multiple cultures: in Hebrew it can connote joy or singing, while in Japanese it is often written with characters meaning "orchid" or other motifs. As such it appears as a given name and in fiction and popular culture.

The many meanings of Ran are usually distinguishable from context: grammar and orthography separate the English verb form from proper nouns; capital letters or acronym usage (RAN) often signal technical or institutional senses; and cultural context indicates the mythological, cinematic or onomastic uses. Each sense has its own terminology and literature for readers who want deeper information.
