Rabia Şermi Kadın (Ottoman Turkish: رابعه شرمی قادین; "spring" and "tranquil"; died; c. 1732;^[3]) was a consort of Sultan Ahmed III and the mother of Sultan Abdul Hamid I.

Her birthplace and date are unknown. She fell victim to the Ottoman slave trade and was placed in the Ottoman Imperial harem as the concubine of Ahmed III. On 20 March 1725 she gave birth to her only son Şehzade Abdul Hamid. In 1728, when he was three she commissioned a fountain in Şemsipaşa, Üsküdar. Ahmed was deposed in 1730, and his nephew Mahmud I ascended the throne. Şermi along with other ladies of Ahmed's harem went to the Eski Palace, at Beyazıt Square.^[3]

Şermi died in 1732 leaving Abdul Hamid motherless at the age of seven he was then entrusted in the care of his elder half-brother Mustafa III, and was buried in the mausoleum of imperial ladies, in the New Mosque in Istanbul.

Abdul Hamid ascended the throne in 1774 after the death of his elder half brother Mustafa III. However, she was never Valide Sultan, as she had died forty two years before Abdul Hamid ascended the throne. He created the Beylerbeyi Mosque in memory of his mother.^[3]

Together with Ahmed, Şermi had one son:

• Abdul Hamid I (Topkapı Palace, 20 March 1725 - Istanbul, Turkey, 7 April 1789, buried in Tomb of Abdul Hamid I, Fatih, Istanbul). He was the 27° Sultan of the Ottoman Empire, after forty-four years of reclusion in the Kafes.
