Petrícek is a masculine name of Czech origin, functioning as an affectionate diminutive form of Petr (the Czech equivalent of Peter). The suffix '-ícek' adds a sense of endearment or smallness to the base name. Petr itself derives from the Greek name Petros, meaning 'rock' or 'stone.' Petrícek would typically be used as a loving nickname within families rather than as a formal given name on official documents. This diminutive form reflects the Czech language's rich tradition of using affectionate variations of names. While uncommon outside of Czech-speaking regions, it carries cultural significance and warmth within Czech families and communities.

The name has remained consistently popular in Eastern European countries for centuries, connected to numerous notable historical figures, artists, and athletes from these regions.
