Meaning & origin

Denny is a classic mid-20th century nickname-turned-given name. It reached its highest popularity in 1946, ranking among the top names of the 1940s. Since 1986, its usage has steadily declined; in 2025, it ranked 4249, with about 1 in 71170 newborn boys receiving the name. The name was most common in Washington state during its peak decades. Denny retains a friendly, unpretentious character typical of short, one-syllable nicknames from the era.

Denny originated as a medieval English pet form of Dennis, which comes from the Greek name Dionysios, meaning 'follower of Dionysus'. The name was popular among early Christians, with Saint Denis being a notable 3rd-century martyr. Denny emerged as an independent given name in the 19th century, particularly in the United States.
