Ivor Bertie Guest, 1st Baron Wimborne, 2nd Baronet, DL (29 August 1835 – 22 February 1914) was a British industrialist and a member of the prominent Guest family.
Guest was commissioned a cornet in the Dorsetshire Yeomanry on 20 April 1858 and was promoted to lieutenant on 11 March 1867.
He held the office of High Sheriff of Glamorgan in 1862 and was the mayor of Poole from 1896 to 1897. In 1879, he rebuilt the real tennis court at Canford. He was lampooned in Vanity Fair as "the paying Guest".
From 1874 on, he stood unsuccessfully for election to the House of Commons as a Conservative, contesting Glamorganshire at the 1874 general election, Poole at a by-election in May 1874, and Bristol at a by-election in 1878 and at the 1880 general election. However, following the tariff reform by Chamberlain, he seceded from the Conservative party and sat in the House of Lords as a Liberal.
He was President of the Dean Close Memorial School from 1902, and a Deputy Lieutenant of Dorset.
