Basaidu (Persian: باسعيدو)[a] is a village in Dulab Rural District of Hara District, Qeshm County, Hormozgan province, Iran.

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.

Further up the Persian Gulf, ports of Apollonia (Obolla) and Apollodorus (Abadan), among others, likewise carry ancient Hellenistic names.

[citation needed] At the time of the 2006 National Census, the village's population was 1,662 in 359 households, when it was in Shahab District.

[5] The 2016 census measured the population of the village as 2,228 people in 520 households.
