Al-Ḥārith ibn Ḥilliza al-Yashkurī (Arabic: الحارث بن حلزة اليشكري) was a pre-Islamic Arabian poet of the tribe of Bakr, from the 5th century.
Ibn Kulthum pleaded the Taghlib's cause by reciting the sixth of the mu'allaqāt.
A quarrel then broke out between Ibn Kulthum and al-Nu'man, the Bakr spokesman, as a result of which the king dismissed them both and asked al-Harith to act as spokesman for the Bakr tribe instead of al-Nu'man.
It is said that al-Harith was an old man by this time, and afflicted with leprosy, so that he was required to recite his poem from behind a curtain.
Although the mu'allaqa is mostly a plea, interspersed with flattery of King Amr, it begins conventionally in the usual style of a qasida with a brief section of regret for a lost love and a description of a flight by camel.
