Sabla Wangel Hailu (Amharic: ሰብለ ወንጌል ሀይሉ; 1895/1896 – 1969) was an Ethiopian aristocrat and the second wife of the uncrowned Emperor of Ethiopia, Lij Iyasu.

[2] At the age of 14, she was selected by the Emperor of Ethiopia, Menelik II, to marry his presumptive heir, Lij Iyasu.

[4] As Lij Iyasu's first, brief marriage to Romane Werq was probably unconsummated, Sabla Wangel may have been his only official wife.

[6] Sabla Wangel's paternal grandfather, Tekle Haymanot of Gojjam, had rebuilt a church at Mängəśtä Sämayat in 1887.

[1] A memorial text written on the modern Sabla Wangel's death in 1969 records: She loved Our Lady Mary deeper in her heart and due to this, she built a wonderful church in her name called Mängəśtä Sämayat, the country of Säblä Wängel the first, the wife of Ləbnä Dəngəl, King of Ethiopia.
