There were many variations of the name Pahang in history. The "Book of Song" referred to the kingdom as "Pohuang" or "Panhuang". The Chinese chronicler Zhao Rugua knew it as "Pong-fong". According to the continuation of Ma Duanlin's "Wenxian Tongkao", Pahang was called "Siam-lao thasi". By Arabs and Europeans, the kingdom was variously styled "Pam, Pan, Paam, Paon, Phaan, Phang, Paham, Pahan, Pahaun, Phaung, Phahangh".
