Basaidu

is a village in Dulab Rural District of Hara District, Qeshm County, Hormozgan province, Iran.

== Etymology == Despite phonetic similarity, Basaidu is not derived from the dynastic name of the Bu Saidi sultans of Oman who in fact ruled Qeshm Island and vicinity until the mid 19th century. Instead, the name is the ancient Greek/Hellenistic Poseidonia, named after the sea god, Poseidon. Further up the Persian Gulf, ports of Apollonia (Obolla) and Apollodorus (Abadan), among others, likewise carry ancient Hellenistic names.
