Gill got the prize after facing stiff competition from England Test skipper Ben Stokes and South African all-rounder Wiaan Mulder.
The 25-year-old enjoyed a remarkable month in July, piling up 567 runs at an outstanding average of 94.50 across three Tests, smashing a double hundred and two hundreds in six outings.
It was Gill's first tour as India's Test captain and the 25-year-old said it was a nice honour to be recognised.
"It feels great to be named the ICC Player of the Month for July," Gill said.
"This time it holds a lot more significance since it has come for my performances during my first Test series as captain.
"The double ton in Birmingham is obviously something I will cherish forever and will be one of the highlights of my tour to England.
"The Test series against England was a learning experience for me as captain and we had some outstanding performances from both sides, which I am sure players from both sides will remember for a long time.
"I would like to thank the jury for selecting me for this award and my teammates who have been with me during the course of this exciting series. I look forward to continuing my form in the season ahead and bring more laurels for the country."
This is Gill’s fourth Player of the Month honour from the ICC, having won previously in February this year, and in January and September, 2023.
