Roger II Trencavel (died March 1194) was the Viscount of Carcassonne, Béziers, Razès, and Albi from 1167 or 1171 until his death. Until 1177 he used the title proconsul, usually as proconsul de Bitteris (of Béziers), but he abandoned the usage when he became a vassal of the Crown of Aragon. His government of his lands was characterised by increasing complexity, such as the development of the offices of seneschal and sub-vicar, but his later years are characterised by financial troubles and a "general malaise" perhaps brought about by his poor relations with the Church hierarchy in light of his favourable attitude towards Catharism.
