This is a list of environmental dates which are designated for creating awareness of environmental issues.

Species awareness days highlight biodiversity, with the aim of increasing understanding and appreciation of the subject. Some of these days have been shown to cause a rise in information-seeking behaviour, and may lead to an increase in conservation fundraising by charities and advocacy groups.
