The Mexican team Club León's home stadium is called the "Nou Camp," which is also the name of the stadium in Spain where FC Barcelona play their home games. However, "Nou Camp" has no meaning in Spanish and I don't believe there are many Catalan speakers in Mexico so I was surprised to encounter a seemingly-Catalan name.
The relevant entry in Spanish-language Wikipedia makes an attempt at explaining where the name came from but it doesn't quite make sense. Here's my translation:
Contrary to what people believe and because of a mistranslation from Spanish, the stadium was erroneously named "Nou Camp", which is the name (in Catalan) of FC Barcelona's stadium. People in Barcelona (?!) started calling their stadium "Camp Nou" (which means "new field" in Spanish), and that's the name that was eventually chosen.
Even if the word Barcelona should be León, I still can't think of what sort of translation error would lead to a Catalan name for a Mexican stadium.
For posterity, here's the Spanish text I made my translation from:
En contra de lo que la gente cree y por una mala traducción del español, se le dio el erróneo nombre de "Nou Camp", que coincidía con el del FC Barcelona, cuyo nombre sí proviene del catalán. La gente en Barcelona empezó a llamarle a su estadio Camp Nou, que en español es Campo Nuevo, y al final fue el nombre elegido.
