Lebanon never officially adopted a coat of arms or emblem. However, various unofficial coats of arms have been used since the proclamation of independence on 7 December 1943. The main variant consists of a red shield with a white bend sinister on which is placed a cedar tree. It is similar to the flag of Lebanon, with the exception of the Spanish fess on the flag being changed into a bend sinister.

Cedrus libani, the cedar of Lebanon or Lebanese cedar, is a species of tree in the genus Cedrus, a part of the pine family, native to the mountains of the Eastern Mediterranean basin. It is a large evergreen conifer that has great religious and historical significance in the cultures of the Middle East, and is referenced many times in the literature of ancient civilisations. It is the national emblem of Lebanon and is widely used as an ornamental tree in parks and gardens.
