Giovannino is an Italian masculine given name, functioning as a diminutive of Giovanni, the Italian form of Iohannes (see John). The name conveys a sense of affection or smallness, often used as a familiar or endearing form, equivalent to "Little John" or "Johnny" in English. While Giovanni has been a staple in Italy since the late Middle Ages and boasted bearers like the writer Giovanni Boccaccio, the painter Giovanni Bellini, and the sculptor Gian Lorenzo Bernini, Giovannino appears frequently in historical records as a variant for younger relatives or commoners. Variants of Giovanni include Gian, Gianni, Giò, and Vanni, but Giovannino is distinct with its diminutive suffix -ino. In art and literature, Giovanni Battista's depiction sometimes uses San Giovannino for John the Baptist as a child, showing the name's connection to religious imagery.
