Leroy C Ioas (15 February 1896, Wilmington, Illinois - 22 July 1965, Haifa, Israel) was a Hand of the Cause of the Baháʼí Faith.
Ioas moved to San Francisco after marrying Sylvia Kuhlman and soon became active in the local Baháʼí community.
In order to fulfill his duties, he quit his job in the railway industry, where he had worked for nearly forty years, and moved to Haifa, where he would reside until the end of his life.
He closely supervised the construction and completion of the Shrine of the Báb, for which Shoghi Effendi named the door on the octagon after him.
[2] After the death of Shoghi Effendi, Ioas was among nine Hands of the Cause elected as a Custodian of the Baháʼí Faith on 25 November 1957.
