Nicolás Todero (Spanish pronunciation: [nikoˈlas toˈðeɾo]; born 15 April 1979) is a former professional tennis player from Argentina.

Todero was born in La Plata, son of Jorge, a tennis coach who later served as Argentina's Fed Cup captain for several years.

It was Roddick's first appearance in a Futures main draw tournament, which gives Todero the distinction of being the first player to defeat the American in a professional match.

[2] Todero started featuring at the Challenger level in 2000, a format in which he won many matches during the years without progressing to a final.

He qualified for his only ATP Tour event, at the 2002 Swiss Open in Gstaad, where he lost in the first round to Austria's Stefan Koubek.
