Birkby is a large multi-cultural suburb close to the town centre in Huddersfield in the United Kingdom, but with a semi-rural atmosphere. The area is home to a large Asian population and there are two mosques in the area. Elsewhere, the suburb contains two Church of England chapels and a Baptist church, as well as a Mormon church.

A very affluent suburb during Victorian times, Birkby was a hot-spot for immigrants due to its cheap housing and proximity to local industry. Amongst local industry includes Hopkinsons' (now Weir) who specialise in valve manufacturing.

The suburb sits in the idyllic Grimescar Valley, a greenbelt area of Huddersfield.
