Calderon has sent a bill to Congress to change the constitution to tweak his nation's official name from Estados Unidos Mexicanos, or United States of Mexico, to plain old Mexico - as the country is already known the world over.
Mexico was given its name of Estados Unidos Mexicanos in the 19th century, when the country's post-revolutionary founders harked to the United States of America as an example of democracy and freedom to follow.
"The name of our country no longer needs to emulate that of other nations," Calderon said. "Forgive me for the expression, but Mexico's name is Mexico."
The country's name is derived from the nomadic Mexica tribe that in 1325 settled present-day Mexico City, which later grew into the imperial Aztec capital before succumbing to Spanish conquerors two centuries later.
Calderon staked his presidency on the much larger issue of fighting the country's drug cartels, and about 60,000 people have died in drug violence during his term. The bloodshed hurt his National Action Party's candidate in a presidential election in July.
He hands Mexico's reins to president-elect Enrique Pena Nieto of the Institutional Revolutionary Party on December 1.
