Luka Doncic may be a Dallas Maverick, but he's clearly never forgotten where he's come from -- 'cause he just sent a bunch of gifts to kids at a hospital in his Slovenian hometown.
TMZ Sports has learned ... the NBA All-Star just directed a special delivery to the Children's Hospital of the University Medical Center Ljubljana -- surprising almost 200 kids with all kinds of goodies to brighten up their holidays.
The shipment was filled with toys -- like LEGOS and dollhouses -- as well as headphones, Jordan sportswear, and gift cards.
We're told Luka also sent each kid an autographed photo and a sweet note from the NBA star ... plus he recorded a video message that everyone got to watch from their hospital bed.
"These children are going through so much," Luka said in a statement. "I just hope this gives them a little bit of happiness during these difficult times."
"I hope they feel better soon, so they can get back to doing what they love. I'm thinking of them and I wish the children and their families a happy New Year in 2022."
Of course, this isn't the first time Doncic has given back to his Slovenian roots ... in 2020, he launched a program with Slovenian athletes Jaka Bijol and Robert Kristan to help the country's healthcare system during the pandemic.
The 22-year-old has also donated to the city of Dallas during the pandemic -- gifting 100 pairs of Jordans to healthcare workers at UT's Southwestern Medical Center.
Doncic also partnered up with Mark Cuban, Dwight Powell and the Mavs' Foundation to donate $500k to the same medical center and Parkland Hospital.
Props for all the generosity, Luka.
