Hugh I (Spanish: Hugo, Catalan: Hug) (c. 965 – 1040), Count of Empúries (Ampurias) from 991, was the son of Gausfred I and his first wife, Ava, daughter of Raymond II of Rouergue.
The division took place on the death of Gausfred, but on the death of Giselbert in 1014, Hugh tried to reunify the counties and invaded the county of his nephew, Gausfred II.
Gausfred obtained the help of Bernard I of Besalú and the Abbot Oliva and the two relations arrived to a peace in 1020.
In 1019, a judicial synod in Girona, presided over by Oliva and Bernard, devolved the allod to Ermesinda.
At about this time, Hugh made enemies of the church by seizing the monastery of San Salvador de Verdera.
