Ali I of Yejju (died June 18, 1788) is a Ras of Begemder, and following the death of Ras Mikael Sehul, Regent of the Emperor of Ethiopia.

He is the son of Abba Seru Gwangul, chieftain of the Yejju, and Woizero Gelebu Faris, daughter of Ras Faris of Lasta.

According to Abir, he founded the town of Debre Tabor, which became the capital of his dynasty.

However, from the accounts in the Royal chronicle Ali is never mentioned as dwelling at Debre Tabor, instead he is more closely tied to Filakit Gereger (called Garagara in the Royal chronicle).
