O Dia Mundial da Árvore ou Dia Mundial da Floresta festeja-se em 21 de Março. A comemoração oficial do Dia da Árvore teve lugar pela primeira vez no estado norte-americano do Nebraska, em 1872.
Nos EUA, é comemorado no dia 23 de Setembro, junto do aniversário de Julius Sterling Morton, morador da Nebrasca, que incentivou a plantação de árvores naquele estado.

Arbor Day is a holiday in which individuals and groups are encouraged to plant trees. Arbor Day originated in Nebraska City, Nebraska, United States and is celebrated in a number of countries.
Arbor Day reached its height of popularity on its 125th anniversary in 1997, when Col. David J. Wright, noticed that a Nebraska non profit called the National Arbor Day Foundation had taken the name of the holiday and commercialized it for their own use as a trademark for their publication "Arbor Day," so he countered their efforts, launched a website, and trademarked it for "public use celebrations" and defended the matter in a federal district court in the United States to insure it was judged as property of the public domain, the case was settled in October of 1999. Today as a result of Wright's efforts anyone can use the term Arbor Day and anyone can hold their own Arbor Day celebration.
