Graulhet () is a commune in the Tarn department in southern France.
It is a centre of tanning. Leather was the main activity before this industry largely relocated to China. Graulhet is crossed by the river Dadou. Graulhet is also one of the last remaining places in the Midi where Mesturets are made traditionally.
The leading physician Marthe Condat was born here in 1886. She became the first woman to be a Professor of Medicine in France.
