Giovanni Battista Ceirano was an Italian entrepreneur and car pioneer. The first motorcar he designed and built was the Well-Eyes, but he sold the rights to Giovanni Agnelli of F.I.A.T. who manufactured it in volume as their first motorcar.

Società Torinese Automobili Rapid, also known as S.T.A.R. and Rapid, was an Italian car manufacturer founded by Giovanni Battista Ceirano in Turin in July 1904. Rapid was its trademark. In 1921 it was acquired by the S.P.A. company that had been founded by Giovanni Battista's brother Matteo Ceirano, and which, in 1925, was taken over by Fiat.
