Drew Brees' recent commercial has left lightning strike victims enraged … with a major organization ripping the NFL superstar's "inappropriate" and "disgusting" stunt.

The New Orleans legend went viral on Friday after he faked getting struck by lightning as part of a promotion with PointsBet USA … duping some people into believing he was actually injured — if not worse.

Lightning Strike and Electric Shock Survivors International — an organization that has members in 13 countries that helps those impacted by similar accidents — got wind of Brees' commercial … and they tell TMZ Sports they're not happy.

"The recent Drew Brees lightning commercial is an inappropriate, disgusting method of promoting gambling or any TV commercial campaign," a statement from LSESSI says.

"This is a deadly injury, and it is disappointing to see the continual ridicule of lightning and electrical injury survivors in comical light in which it is presented for commercial gain and profit."
