Henry I of Ziębice (Polish: Henryk I Ziębicki; c. 1350 – aft.

He was the second and youngest son of Nicholas the Small, Duke of Ziębice, by his wife Agnes, daughter of Herman Krušina of Lichtenberg.

After his father's early death in 1358, Henry I and his older brother Bolko III succeeded him in the Duchy of Ziębice as co-rulers; however, because they are minor at that time, their mother, the Dowager Duchess Agnes held the regency on their behalf until 1360, when Bolko III assumed the government of the Duchy by himself and take the guardianship of his brother.

In order to avoid further divisions of the already small Duchy of Ziębice, Henry I was destined since his early youth to a Church career.

On 17 August 1360 he received from Pope Innocent VI the Canonry of the Chapter of Wroclaw, although is known that he early received the prebendary of the Church of Holy Cross, also in Wroclaw.
