Ivor Churchill Guest, 1st Viscount Wimborne, KP, PC, known as Lord Ashby St Ledgers from 1910 to 1914 and as Lord Wimborne from 1914 to 1918, was a British politician and one of the last Lords Lieutenant of Ireland, serving in that position at the time of the Easter Rising.

The Easter Rising, also known as the Easter Rebellion, was an armed insurrection in Ireland during Easter Week in April 1916. The Rising was launched by Irish republicans against British rule in Ireland with the aim of establishing an independent Irish Republic while the United Kingdom was fighting the First World War. It was the most significant uprising in Ireland since the rebellion of 1798 and the first armed conflict of the Irish revolutionary period. Sixteen of the Rising's leaders were executed starting in May 1916. The nature of the executions, and subsequent political developments, ultimately contributed to an increase in popular support for Irish independence.
