Henry Gabriels (October 6, 1838 – April 23, 1921) was a Belgian-born prelate of the Roman Catholic Church who served as bishop of the Diocese of Ogdensburg in Northern New York from 1892 until his death in 1921.

He asked Bishop Louis-Joseph Delebecque of Ghent to suggest some priests who might want to work at the new St. Joseph's Seminary in Troy, New York.

In 1868, Gabriels learned about a small community of German and Irish Catholics near Sand Lake, New York, who did not have a church or a priest.

Since Gabriels spoke some German, he started spending time there, celebrating mass in a private residence and organizing a new parish.

[4] He received his episcopal consecration on May 5, 1892, from Archbishop Michael Corrigan, with Bishops Francis McNeirny and Patrick Anthony Ludden serving as co-consecrators, at the Cathedral of the Immaculate Conception in Albany, New York.

[3]On August 1, 1906, Gabriels met in Rome with Pope Pius X, giving him a message from U.S. President Theodore Roosevelt and a Peter's Pence contribution of $1350.

[7] His nephew Henry E. Gabriels, born in Belgium, graduated as a civil engineer from Rensselaer Polytechnic Institute in 1910.
