Count Wilhelm I of Henneberg-Schleusingen (* 31.) July 1384; † 17. July 1426 during a pilgrimage to Jerusalem on Cyprus) was reigning Count of Henneberg-Schleusingen.

His parents were Count Henry XIII of Henneberg († 26 December 1405) and his wife Mathildis von Baden, a daughter of Count Rudolf von Baden. His father – to the chagrin of his son – left his mother the offices Schleusingen and Suhl as Wittum.

At the age of 21, he took over the government business. His father had left many debts and so it became his job to reorganize the finances. His mother gave him the castle Mainberg. He sold half the castle on 31 August 1411 to Johann von Cronberg and his wife. The Knights of Wenkheim also made claims to the castle, but in 1426 Emperor Sigismund confirmed all fiefdoms and also the castle.

He was named in 1414 under the patrons of the Kostnitz Council. On a pilgrimage to Jerusalem he died on the way to the island of Cyprus on the 17th. July 1426.

He married around 1411 Anna von Braunschweig († 27 October 1426), a daughter of Otto von Braunschweig-Göttingen. She was the widow of Margrave Wilhelm I. von Meissen († 10 February 1407) and she was said to have a good household. Their son Wilhelm II inherited the county, further descendants were:
Anna (* 1421) ⚭ Johann von Heideck
Elisabeth († 14 November 1444) ⚭ Friedrich I of Henneberg-Römhild († 24). September 1422
