Miss Earth 2021

Miss Earth 2021 was the 21st edition of the Miss Earth pageant, held virtually on November 21, 2021 due to the ongoing COVID-19 pandemic.

Destiny Wagner of Belize won the event, as was crowned by Lindsey Coffey of the United States.

At the same event, the other elemental winners were also crowned: Marisa Butler of the United States won Miss Earth Air, Romina Denecken of Chile won Miss Earth Water, and Jareerat Petsom of Thailand won Miss Earth Fire.

Contestants from 80 countries and territories participated in this pageant, which was hosted by James Deakin for the fifth consecutive time, and Miss Earth 2017 Karen Ibasco.

The pageant was confirmed to take place on November 21, 2021.
