Cândido Godói (Portuguese pronunciation: [ˈkɐ̃dʒidu gɔˈdɔj]) is a municipality of 6,151 inhabitants in the state of Rio Grande do Sul, Brazil near the Argentine border, famous for the high number of twins born there.

The twin phenomenon is centered in Linha São Pedro, a small settlement in the city of Cândido Godói, in an ethnically homogeneous population of German descent.

The Argentine historian Jorge Camarasa has suggested that Mengele conducted experiments on women in the area, which could be responsible for the high ratio of twins.

[4][9] However, such speculation has been disputed by local historian, Paulo Sauthier, who says Mengele did not study twins during his time in Brazil.

[11] This phenomenon of a large number of twin births is not unique to Cândido Godói, and has also been observed in the town of Igbo-Ora in Nigeria and the village of Kodinhi in India.
