Plocama is a genus of flowering plants in the family Rubiaceae. It was described by William Aiton in 1789. It is distributed from the Canary Islands to northwestern India.

The genus was expanded in 2007 when several other Rubiaceae genera were merged into it. There are now about 34 species.

Plants of this genus are herbs or shrubs. They generally have an offensive scent when crushed. The leaves are oppositely arranged. The corolla is funnel shaped with a short to long tubular base. The fruit is either a drupe or a body that splits into two parts when ripe.
