Rihanna‘s dad, Ronald Fenty, died from cancer, pneumonia and other serious illnesses … TMZ has learned.

Fenty’s death on May 30 was caused by acute respiratory failure, pancreatic cancer and aspiration pneumonia — which is a bacterial lung infection — according to a death certificate obtained by TMZ.

Other causes listed in the document include acute renal failure and acute tubular necrosis — both of which involve extensive kidney damage.

TMZ broke the news that Ronald died last month at Cedars-Sinai Medical Center in L.A.

Rihanna and Ronald had a rocky relationship through the years … the two were estranged for a long period of time before eventually reconciling.

Back in February 2023, Ronald told TMZ he was over the moon about his daughter and A$AP Rocky expecting another child together, and was eager to be a part of the baby’s life.

Ronald was 71.
