Ái Châu (chữ Hán: 愛州) was a historical province of Vietnam under the third Chinese domination (Bắc thuộc) roughly equivalent to Thanh Hóa Province today.
In 989 after an upland chieftain, named Dương Tiến Lục, had reported to Lê Hoàn that local militia from the aboriginal prefectures of Ái Châu and Hoan Châuse planned to resist Lê controlt, the king authorised an attack on the prefectures.
