Randy Gonzalez, the father in the popular TikTok duo Enkyboys, has died ... following a battle with cancer.

A source close to the family tells TMZ, Randy passed Wednesday morning in hospice after his struggles with colon cancer ... a health battle he provided updates about throughout his fight.

Randy broke the news about his condition back in April, telling fans he was diagnosed about 6 months prior, and given 2-3 years to live. He said chemotherapy could extend things a possible 5 more years.

The viral star created a GoFundMe to help pay for his treatments -- after he claimed he was denied at a cancer center at the University of Texas -- stating they didn't take his insurance.
