Donny is a masculine name most commonly used as a diminutive of Donald, which derives from the Scottish Gaelic name Dòmhnall, meaning "world ruler" or "world mighty." The name gained significant popularity in the mid-20th century, particularly in the United States, partly due to the fame of performers like Donny Osmond. Donny has a friendly, approachable quality that maintains the strength of Donald while adding a more casual, boyish charm. Though its usage as a formal given name has declined since its peak, it remains recognized as both a nickname and standalone name. Donny carries a nostalgic appeal for many, evoking the easy-going American culture of the 1960s and 1970s, while still functioning as a personable, unpretentious option for boys today.
