The name Leroy is a French given name with origins dating back to the Middle Ages. It is a masculine name derived from the Old French words "le" meaning "the" and "roy" meaning "king" or "ruler". The name essentially means "the king" or "the regal one".

In its earliest forms, the name was spelled in various ways such as Leeroy, Leroy, or Leroi. It was a popular name among the French nobility and upper classes during the medieval era, as it conveyed a sense of royalty and power.

One of the earliest recorded instances of the name can be found in the Chronicle of Saint-Denis, a historical record from the 12th century, which mentions a nobleman named Leroy de Montfort. However, the name's origins may date back even further, as it is believed to have been used during the time of the Frankish kings in the 5th and 6th centuries.

The name Leroy also has a historical connection to the American South, where it was popularized among African American families during the post-Civil War era. One of the most famous individuals with this name was Leroy "Satchel" Paige (1906-1982), a legendary baseball pitcher who played in the Negro Leagues and later in Major League Baseball.
