Byculla is a suburb of Mumbai. It is also the name of a railway station on the Mumbai suburban railway on the Central Railway line.

Byculla houses the city zoo called Veermata Jijamata Prani Sangrahalay or Ranichi Baug in Rani Jijamata Udyaan (Rani Bagh) (earlier called Victoria Gardens). There are talks of shifting the zoo to a more spacious location.

Byculla also houses the Veermata Jijamata Mueseum (earlier Victoria and Albert Museum). It was built in 1871 and is a near replica of its namesake in London.

Byculla is also home of the Byculla Vegetable Market, the largest vegetable market in Mumbai (even larger than Crawford Market).

Byculla used to house many of the city's textile mills until the mills shut shop and moved out of the island city. As of today, few mills are operational and even they are on the brink of closure. Many of these old mills are now desolate and some are being razed down to make way for newer constructions.
