Kapho (, ) is a district (amphoe) in Pattani province, southern Thailand.
The minor district (king amphoe) Kapho was formed on 15 March 1982 by splitting off three southern tambons from Sai Buri district. On 4 November 1993 it was upgraded to a full district.
Neighboring districts are (from the northwest clockwise): Thung Yang Daeng and Sai Buri of Pattani Province; Bacho of Narathiwat province; and Raman of Yala province.
The district is divided into three sub-districts (tambons), which are further subdivided into 22 villages (mubans). There are no municipal (thesaban) areas. There are three tambon administrative organizations (TAO).
