The given name Dennison is believed to have originated as an English surname derived from the medieval personal name Dennis. Dennis itself is thought to be a variant of the Greek name Dionysios, which means "follower of Dionysos," the Greek god of wine, vegetation, and fruitfulness.
The earliest recorded use of the name Dennison as a given name dates back to the 16th century in England. One of the earliest known bearers of the name was Sir William Dennison (c. 1530-1594), an English landowner and member of Parliament during the reign of Queen Elizabeth I.

One notable figure from this period was Major-General Daniel Dennison (c. 1615-1682), an English-born military officer and colonial leader in Massachusetts.
During the 18th and 19th centuries, the name Dennison continued to be used, though it remained relatively uncommon. One notable bearer was Thomas Dennison (1786-1864), an American lawyer and politician who served as a U.S. Representative from Pennsylvania.
In the 20th century, the name Dennison gained more widespread usage, particularly in the United States. One prominent figure was William H. Dennison (1888-1960), an American businessman and politician who served as the 52nd Governor of Ohio from 1949 to 1957.
