Captain Bush Lane, now officially known as Soi Charoen Krung 30 (Thai: ซอยเจริญกรุง 30), is a side-street (trok or soi) branching off Charoen Krung Road in Bang Rak District of Bangkok, Thailand. It was home to several members of Bangkok's early European expatriate community during the turn of the 19th–20th centuries, including Captain John Bush, an influential English sea captain after whom the street is named.
