London Rivers Week is a week-long annual campaign inspiring the public to celebrate all of London’s rivers and the many projects taking place to protect them. This year’s edition marks its tenth anniversary and is happening between the 23rd and 31st May. The overarching theme for 2026 is: “Know Your Local River” - encouraging Londoners to identify, explore and connect with their nearest river. The celebrations will highlight a decade of river restoration successes and showcase the achievements of the communities who have helped bring London’s rivers to life.
