Gerald Walter Erskine Loder, 1st Baron Wakehurst, JP DL LLB (25 October 1861 – 30 April 1936) was a British barrister, businessman and Conservative politician. He is best remembered for developing the gardens at Wakehurst Place, Sussex.
The fourth son of Sir Robert Loder, 1st Baronet, Member of Parliament for New Shoreham, Loder was educated at Eton and Trinity College, Cambridge. He became a barrister at the Inner Temple in 1888.
Loder was Conservative Member of Parliament for Brighton from 1889-1905. He was private secretary to the President of the Local Government Board (Charles Ritchie) from 1888-92 and to Lord George Hamilton (the Secretary of State for India) from 1896-1901. He served briefly under Arthur Balfour as a Lord of the Treasury in 1905.
A keen gardener, Loder purchased the Wakehurst Place estate in 1903 and spent 33 years developing the gardens, which today cover some two square kilometres (500 acres) and are owned by the National Trust. He was President of the Royal Arboricultural Society from 1926-27 and President of the Royal Horticultural Society from 1929 to 1931. He was a Director of the London, Brighton and South Coast Railway from 1896, and served as its last Chairman in December 1922. He was a director of its successor, the Southern Railway, and later Chairman from 1934 until his resignation in December 1934. In June 1934 he was raised to the peerage as Baron Wakehurst, of Ardingly in the County of Sussex.
