Lo Lung Hang (Chinese: 老龍坑) is a valley northwest of Hung Hom, Kowloon City District, Hong Kong. The place is west of Hok Yuen and it is where the Valley Road Estate was once located. The valley is less visible now, but there is still a street remaining called Lo Lung Hang Street, near Hung Hom MTR station.
