What is the meaning of the name Billy ?

The baby name Billy is a Male name , 2 syllables long and is pronounced /ˈbɪli/ (BIL-ee).

Billy is in Origin.

Billy is the English diminutive of William, from Norman French Guillaume and ultimately the Germanic elements wil “will, desire” + helm “helmet, protection,” yielding the meaning “resolute protector.” It emerged in Middle English as a pet form alongside Will and Bill, with the initial B- likely arising through rhyming alteration (Will > Bill > Billy). As a standalone given name, Billy gained popularity in the late 19th and mid-20th centuries across the English-speaking world, then declined, now most common as an informal short form for William.

Variants include Bill, Willie/Willy, and the spelling Billie, widely used as a unisex or especially feminine form in the 20th century. Related forms in other languages derive from local equivalents of William (e.g., German Wilhelm, Spanish Guillermo, French Guillaume) but do not typically use Billy. Notable cultural bearers - such as Billy Graham and Billy Joel - have kept the nickname familiar and approachable.
