So named because it is the time when the antlers of buck deer regrow. "Buck Moon" is a term for the July full moon. Early references to the Buck Moon claim that it is a "Native American" term without specifying a language or nation. More recently it is sometimes claimed to be Algonquin; if this is true, it appears to be a less prominent term. Miskomin Kìzis, commonly translated as "Strawberry Moon" seems to be more common, at least as far as I can tell from internet searches. Takiyuḣa-wi, "Deer Rutting Moon," seems to exist in the Lakota language and more or less coincide with July, however.
