Peter John Seabrook MBE was a British gardening writer and television broadcaster, presenting programmes including the BBC's Gardeners' World. He wrote a gardening column in The Sun newspaper for over 40 years. He was appointed an MBE in 2005.

Gardeners' World is a long-running British gardening programme, first broadcast on 5 January 1968. The 2024 series is the 55th. Its first series was presented by Ken Burras and came from Oxford Botanical Gardens. Up until 2020 most of its episodes have been 30 minutes in duration; however, this changed in spring 2020 when the format was extended to an hour. All episodes in the 2021 series onwards follow this 60-minute format. Gardeners' World currently airs between mid-March and late October on BBC Two every Friday. The programme usually takes a four-month winter break from November to February.
