Let's Do It World is a global civic organization that started from Estonia, mobilizing people worldwide in joining local, national and regional clean-up events. Among other projects, it is the founder of World Cleanup Day, on which a network of 180 countries, with over 21.2 million participants took place in 2019. First time in 2024 World Cleanup Day mobilises millions in its first year as a UN International Day.

The Let's Do It! organization was first conceived in Estonia in 2008, where a country clean-up action called Let's do it! (in Estonian: "Teeme ära!") cleaned up 10000 tons of illegal waste by more than 50000 volunteers in one day. Following Estonia's lead, many countries also started their own country clean-up events.

Let's Do It! World is an accredited member of the United Nations Environment Programme (UNEP).

Since 2017, the movement uses the hand gesture W sign, aka "Three Fingers Up," as its symbol.
