Atibaia (or Estância de Atibaia) is a Brazilian municipality in the state of São Paulo, Brazil. The name is derived from an indigenous language called Tupi, and means "healthy water river". Its name has changed over time, from the primitive Tupi word Tybaia, to Thibaia, Atubaia, Thibaya, and finally the city's modern name, Atibaia.
Its strawberry crops are well known. These crops are cultivated mainly by Japanese descendants, since the city was a common Japanese immigrant center.
