11:05 AM PT — Danny confirmed the rumors are fake saying … “Thank you all for your concern but I am very much alive. Someone is spreading fake news.”

Danny Trejo fans got a real scare over the weekend when a post claiming the beloved actor died went viral … but DT is just fine, TMZ confirmed.

It all started when remembrance started to circulate on Instagram … and the hoax really took off when John Leguizamo shared it.

The actors were both in “The Infiltrator” … so it stands to reason JL might know if something had happened to Danny! So, yeah, there was a panic!

But, again, we’re told by his rep that it’s all just a hoax … Danny is fine.

Ironically, that last time we caught up with Danny, it was to talk about the shocking death of Val Kilmer — a pal of his who he co-starred with in the classic, “Heat.”

Danny wanted to set the record straight that Val was cool to everyone on a film set — he simply believed if something could be done better, he wanted it done that way. And that ain’t the same as a star being a blowhard for ego’s sake.

Danny says the only issue he ever had with Val … his pal didn’t get nominated for an Oscar as Doc Holliday in “Tombstone.”
