Russell and Ciara revealed the amazing contribution on Tuesday ... saying they gave ten different nonprofits in Denver $100k each.

The 9x Pro Bowler and Ciara -- who is pregnant with their third child -- hand over massive checks to "deserving organizations"  ... in partnership with their Why Not You Foundation and Common Spirit Health.

"We are forever grateful for the opportunity to impact our youth!" Wilson said.

"Today, we celebrated 10 deserving organizations which will each receive $100,000 to support their remarkable work in health equity, education, food security, social justice, and support for children and youth."

Of course, the gesture comes days after the Broncos lost a close Thursday Night Football game to the Chiefs, bringing their record to 1-5 record, putting them in last place in the AFC West.

Fans had high expectations when they landed the Super Bowl champ in a trade back in March 2022 ... giving him a 4-year, $245 million extension.

But, the 34-year-old quarterback hasn't been good ... he's 5-16 as the starter, and was sacked 55 times last season, the most in his NFL career. This year hasn't been much better.

However, Broncos' new head coach Sean Payton says the blame shouldn't be entirely on Russ.

"We got to be able to throw it better to win in this league, and that wasn’t directed at one player," Payton said after the TNF loss, "It was directed at all of us on offense."

Despite the struggles in Broncos Country, Wilson hasn't let the on-field struggles slow down his philanthropy.
