London Rowing Club is the second oldest of the non-academic active rowing clubs on the Thames in London, United Kingdom. It was founded in 1856 by members of the long-disbanded Argonauts Club wishing to compete at Henley Royal Regatta.

Henley Royal Regatta is a rowing event held annually on the River Thames by the town of Henley-on-Thames, England. It was established on 26 March 1839. It differs from the three other regattas rowed over approximately the same course, Henley Women's Regatta, Henley Masters Regatta, and Henley Town and Visitors' Regatta, each of which is an entirely separate event.
