Old Paradise Gardens (formerly known as Lambeth High Street Recreation Ground, and informally as the Rec) is a 0.76 hectares (1.9 acres) park in Lambeth in the London Borough of Lambeth in London, England, and opened to the public in 1884. Before it became a park, it was a burial ground of St. Mary's Church, Lambeth from 1703 to 1853.

By the early 18th-century the churchyard of St Mary's, Lambeth was full. In order to provide an alternate burial ground for the parish, Archbishop Tenison acquired a market garden in 1703 for the sum of £120.^[1] It was consecrated in 1705.^[2] It was extended in 1814, and the extension was consecrated in 1816.^[1] A watch house was erected in 1825.^[1] The burial ground closed in 1853.^[1]

By 1880 the former burial ground was unsightly, and the Lambeth vestry decided to turn it into a public garden, which opened in 1884.^[1] In 1929 the recreation ground was extended with the acquisition of the site of a glass bottle factory in Whitgift Street.^[1] However, by the 1970s the recreation ground had been allowed to deteriorate, and had been largely asphalted over. It has subsequently been restored, and re-landscaped with grassy mounds, a water feature, seating and shrubs and spring bulbs planted.^[1] Spring bulbs were donated by the Metropolitan Public Gardens Association.^[3]

The former watch house is commemorated with a plaque.^[1] There were mortuary buildings in the north east corner, which were removed at the time of the restoration in the 1970s.^[4]

Gravestones are located around the perimeter of the walls of the gardens; the walls themselves are Grade II listed,^[4] and were on the Heritage at Risk Register.^[5] Following restoration work in 2021, they have been removed from the register.^[6]

In 2013 the park was again refurbished, with new entrance gates, and renamed Old Paradise Gardens.^[1][2]

The Garden Museum run weekly gardening sessions for local residents in the gardens.^[7] Future proposals include establishing a cut-flower business, in order to provide revenue for maintenance.^[1] Other proposals include wildflower planting to match that at the Garden Museum.^[6]
