Friday is Oscar De La Hoya's 49th birthday, but the Golden Boy did more giving than receiving on his special day ... by preparing and handing out meals to the critically ill.
TMZ Sports has learned ... ODHL and his GF, Holly Sonders, hit up Project Angel Food in L.A. to give back to the community as part of his bday celebration.
The boxing legend and his lady helped by preparing food and packaging them for those who have a high risk of COVID infection or living with COVID.
Check out the footage -- Oscar's meals even have a personalized label featuring his picture and a special message of encouragement for the recipient.
Of course, COVID-19 hit close to home for Oscar and Holly -- in fact, De La Hoya was hospitalized for 3 days with the virus ... and was forced to back out of his fight against Vitor Belfort.
Because of his experience, Oscar says he knew he wanted to help out in any way he could.
But, don't worry -- there was also some celebrating going on ... with Oscar cutting up an incredible customized cake to share with everyone.
