Ma Tau Wai is an area located in the Kowloon City District of Kowloon, Hong Kong. Historically, it functioned as a walled village situated between what are now known as Argyle Street and Prince Edward Road West.
The location was positioned to the east of the site currently occupied by St. Teresa's Hospital. While it originated as a distinct walled settlement, it is now recognized as part of the broader urban landscape of the Kowloon City District.
