Henry Gray, Jr. (January 19, 1816 – December 11, 1892) was an American lawyer and politician who served in the state legislatures of Mississippi and then Louisiana.

In April and early May 1862, Gray organized the 28th Louisiana Infantry Regiment at Camp Taylor and was elected as its colonel.

Department commander Edmund Kirby Smith ordered his promotion to brigadier general on April 8, however the Confederate Congress disallowed it.

He was promoted to brigadier general on March 17, 1865, backdated to the Mansfield fight, and Gray rejoined his brigade in Polignac's Division until the end of the war.

At the age of 76, Gray died at his daughter's house near Coushatta, Louisiana, and was buried nearby in Springville Cemetery.

Gen. Henry Gray Chapter #218 of the Military Order of the Stars and Bars in Shreveport, Louisiana, is named in his honor.
