The Leader of His Majesty's Most Loyal Opposition, more commonly referred to as the Leader of the Opposition, is the person who leads the Official Opposition in the United Kingdom. The position is seen as the shadow head of government of the United Kingdom.

By convention, the Leader of the Opposition is the leader of the largest political party in the House of Commons that is not in government. When a single party wins outright, this is the party leader of the second-largest political party in the House of Commons. The Leader of the Opposition is often viewed as an alternative or shadow prime minister, and is appointed to the Privy Council. They lead an Official Opposition Shadow Cabinet, which scrutinises the actions of the Cabinet and offers alternative policies.

In the nineteenth century, party affiliations were generally less fixed and the leaders in the two Houses were often of equal status. A single and clear Leader of the Opposition was only definitively settled if the opposition leader in the House of Commons or House of Lords was the outgoing prime minister. However, since the Parliament Act 1911, there has been no dispute that the leader in the House of Commons is pre-eminent and has always held the primary title.

The Leader of the Opposition is entitled to a salary in addition to their salary as a Member of Parliament.
