Tini Beg (Turki/Kypchak: تینی بک; died 1342), also known as Dinibeg, was Khan of the Golden Horde from 1341 to 1342.

He was born to Öz Beg Khan and his principal wife Taydula Khatun.

Muslim sources such as Ibn Battuta claimed that he was the most favored son of Öz Beg and was designated his heir.

[3] The poet Qutb translated Nizami's "Khosrow and Shirin" for Tini Beg and his wife Malika Khatun.

[2] He was considered pro-Christian[7] and received some letters from Pope Benedict XII, who encouraged him to convert to Christianity.
