伦敦图书馆（英语：London Library）是英国伦敦的一座图书馆，也是世界规模最大的图书馆之一，创建于1841年。伦敦图书馆自1845年以来就位于圣詹姆士广场。

The London Library is one of the world's largest independent lending libraries, and one of the UK's leading literary institutions. It was founded in 1841 on the initiative of Thomas Carlyle, who was dissatisfied with some of the policies at the British Museum Library. It is located at 14 St. James's Square, in the St James's area of the City of Westminster, London, which has been its home since 1845. Membership is open to all, on payment of an annual subscription; and life and corporate memberships are also available. As of March 2015 the Library had 6,708 members.
