The Whig government of the United Kingdom of Great Britain and Ireland that began in November 1830 and ended in November 1834 consisted of two ministries: the Grey ministry (from 1830 to July 1834) and then the first Melbourne ministry.

The first wholly Whig government since 1783 came to power after the Duke of Wellington's Tory government lost a vote of no confidence on 15 November 1830. The government, led by the Earl Grey, passed the Great Reform Act in 1832, which brought about parliamentary reform, and enacted the Slavery Abolition Act 1833, bringing about the abolition of slavery in most of the British Empire.^{[citation needed]}

However, King William IV dismissed Grey's successor Lord Melbourne in 1834 and asked Sir Robert Peel to form a government. Peel was out of the country at the time, so the Duke of Wellington formed a caretaker government.^{[citation needed]}
