Saint-Viâtre (French pronunciation: [sɛ̃ vjatʁ]) is a commune in the Loir-et-Cher department in central France.

[3] The village was originally called Tremblevif, from the Latin for "aspen" and "village", but suggesting in the popular imagination a place prone to swamp fever and trembling limbs.

In 1854, worried that outsiders might be put off, the villagers successfully petitioned to change the name to Saint-Viâtre [4] in honour of a hermit, traditionally known as Viâtre, who had lived in the forests of Sologne.

His tomb is in the crypt of the village church.
