Sunyer II (c. 840–915) was the count of Empúries from 862 and Roussillon from 896 until his death.
[1] He and his brother Dela obtained the county of Empúries in 862 after Humfrid, margrave of Gothia, rebelled.
In 878, the council of Troyes deposed Bernat of Gothia, who had held Roussillon since 865.
Together with Dela, he tried to occupy Girona, but their cousin, Wilfred the Hairy, stopped them.
In 891, he prepared a naval expedition to attack Moorish Almería.
