Simurgh (/ˌsɪˈmərɡ/), also spelled simorgh, simorg, simurg, simoorg, simorq or simourv, is a benevolent, mythical bird in Iranian mythology and literature. It is sometimes equated with other mythological birds such as a "Griffin" or "Phoenix" (Persian: ققنوس quqnūs or عنقا anqâ) (which it shares several similarities with), Persian Humā (Persian: هما). The figure can be found in all periods of Iranian art and literature and is also evident in the iconography of Georgia,medieval Armenia, the Byzantine Empire, and other regions that were within the realm of Persian cultural influence.
The New Persian word sīmurğ () derives from Middle Persian sēnmurw (and earlier sēnmuruγ), also attested in Pazend texts as sīna-mrū. The Middle Persian term derives in turn from Avestan mərəγō Saēnō "the bird Saēna", originally a raptor, likely an eagle, falcon, or sparrowhawk, as can be deduced from the etymological cognate Sanskrit śyenaḥ ("raptor, eagle, bird of prey") that also appears as a divine figure. Saēna is also a personal name, which is root of the name. The word was also borrowed into Armenian as siramarg (, ‘peacock’).
