Crindau (Welsh: Crindai) is a Victorian inner-city area just north of the city centre in Newport in south-east Wales.

After the Borough Extension Act of 1876 and the new Marshes Road entrance from Old Green opened, Newport Corporation began construction of the Marshes estate, streets named after Newport mayors and was completed in 1901, the remainder of the land becoming Shaftesbury Park.

More land was acquired to the north of Crindau Pill, along the eastern side of the railway, and a gas and glass works were opened in 1886.

The same year the Newport Workmens Cottage Company was established and built terraced houses for the poor at cheaper rates, (Albany, Agincourt (formerly Arlington), Ailesbury, Argyle, Adelaide, Aragon and Alderney) in between the works and the Marshes up until its dissolution in 1899.

Post-war redevelopments such as the M4 motorway in the 1960s and older housing clearances in the 1970s changed the landscape of Crindau.
