Fossil Fools Day is an international environmental demonstration day on April 1 annually. The name is a play on the terms "Fossil Fuels" and "April Fools' Day."

Fossil Fools Days have been held in many cities around the world. Larger demonstrations have been organized by environmental organizations such as Energy Action Coalition and Rising Tide. These events oppose energy derived from fossil fuels, promote education about alternative sources of energy, and encourage support for climate justice, strong legislation, corporate responsibility and a clean renewable energy future. Protests may also encourage citizens to do their part with lifestyle changes such as riding bikes, reducing electricity usage, and investing in solar or wind energy for their homes.
