The Big City Plan is a major development plan for the city centre of Birmingham, England. Stage 2 of the Big City Plan, the City Centre Masterplan was launched on 29 September 2010. This masterplan sets out how the city centre of Birmingham will be improved over the next 20 years. The plan identifies five key areas of development potentially worth £10 billion. The aim of this ambitious plan will be to increase the size of the city core by 25%, improving transport connectivity throughout the seven ‘quarters’ that make up the city centre.

Sir Herbert Manzoni was made city engineer of Birmingham and his work included the construction of the Inner Ring Road, Middle Ring Road and the Outer Ring Road, which necessitated the purchase and clearance of vast areas of land. As well as this, he designated large areas of land redevelopment areas and set about clearing large areas of slums. The elevated roadways and the ring roads gave Birmingham the tag; "Britain's motor city". One commentator described Manzoni's vision of Birmingham as a "Godless, concrete urban hell", another a "brutalist, concrete-dominated slave to the motor car"". In the mid-1980s, Birmingham City Council decided that they needed to change the image Birmingham had to the public, and improve the livability of the city. The first main aim was to
