The London Necropolis Company (LNC), formally the London Necropolis & National Mausoleum Company until 1927, was a cemetery operator established by Act of Parliament in 1852 in reaction to the crisis caused by the closure of London's graveyards in 1851. The LNC intended to establish a single cemetery large enough to accommodate all of London's future burials in perpetuity. The company's founders recognised that the recently invented technology of the railway provided the ability to conduct burials far from populated areas, mitigating concerns over public health risks from living near burial sites. Accordingly, the company bought a very large tract of land in Brookwood, Surrey, around 25 miles (40 km) from London, and converted a portion of it into Brookwood Cemetery. A dedicated railway line, the London Necropolis Railway, linked the new cemetery to the city.

Brookwood Cemetery, also known as the London Necropolis, is a burial ground in Brookwood, Surrey, England. It is the largest cemetery in the United Kingdom and one of the largest in Europe. The cemetery is listed a Grade I site in the Register of Historic Parks and Gardens.
