Sir Joseph William Bazalgette CB (; 28 March 1819 – 15 March 1891) was a 19th-century English civil engineer. As chief engineer of London's Metropolitan Board of Works, his major achievement was the creation (in response to the Great Stink of 1858) of a sewerage system for central London which was instrumental in relieving the city from cholera epidemics, while beginning to clean the River Thames. He was also the designer of Hammersmith Bridge.
