World Otter Day is celebrated every year on the last Wednesday of May. This day was founded by the International Otter Survival Fund (IOSF). In 2009, it started as Otterly Mad Week and became International Otter Awareness Day in 2014. In 2016 the annual event evolved into World Otter Day. World Otter Day is observed to raise awareness about otters and their protection.
World Otter Day will be celebrated on Wednesday, May 31, 2023.
