Ernest Charles Bavage Locke (9 September 1856 – 5 February 1937) was an Australian politician who was a member of the Legislative Assembly of Western Australia from 1897 to 1901, representing the seat of Sussex.

His cousin, Charles Layman, was also a member of parliament.

Locke farmed at Wonnerup for much of his life, but his chief interest was horse racing, both as a breeder and owner.

With his brother, he won the 1886 Mooney Valley Cup with Isonomy and the 1893 Railway Stakes with Lockeville, as well as many other races.

[2] In retirement, Locke lived in Busselton and later in Perth, dying there in February 1937 (aged 80).
