Bilbrook is a village and civil parish in the South Staffordshire district of Staffordshire, England. It is situated close to the border of the West Midlands, just outside Wolverhampton. Bilbrook is classed as part of the Codsall built-up area by the Office for National Statistics, but retains its own parish council. The village gets its name from billers, which grew in the local Moat Brook until recent times.
