Shihabuddin Sharaful-udaba Sabir (Persian: شهاب‌الدین شرف‌الادبا صابر) known as Adib Sabir (ادیب صابر), was a 12th-century Persian^[1] poet. Originating from Termedh, he was employed in the court of Sultan Sanjar.

He is said to have also been used by the Sultan as a spy against the Sultan's enemies, who eventually drowned him in the Oxus in 1143 AD.

His Persian poetry writings are fluent and refined in style.^{[citation needed]}
