Sonny
SUH-nee
Sonny originated as an English nickname and term of endearment meaning “little son.” For most of the 20th century, it functioned primarily as a nickname rather than a formal given name, carrying an informal, affectionate quality.
The name’s most famous bearer was Sonny Bono (1935-1998), the entertainer and politician who rose to fame as half of the duo Sonny & Cher in the 1960s. He later served as mayor of Palm Springs, California, and as a US congressman.
In fiction, Sonny Corleone from Mario Puzo’s The Godfather (1969) and its landmark 1972 film adaptation gave the name a tough, Italian-American association.
What the name Sonny means
James Caan’s portrayal of the hot-tempered eldest Corleone son made the character an enduring cultural reference.
Sonny was used sparingly as a formal name for decades but has surged recently. In 2015, it ranked No. 824 with just 275 births. By 2024, it reached its all-time US peak at No. 335 with 1,034 births, nearly quadrupling in under 10 years.
The revival connects to a broader trend of informal, vintage nicknames being registered as full legal names rather than diminutives. The rise of Buddy, Teddy, Frankie, and similar names reflects the same impulse.
Sonny has even stronger traction in the United Kingdom and Australia, where it has ranked considerably higher in recent years. In England and Wales, Sonny entered the top 50 in the early 2020s.
The name’s warmth, simplicity, and built-in cheerfulness give it a broad appeal that crosses class and cultural boundaries. At just 5 letters and 2 syllables, it is effortlessly friendly.
