Pakenham horse trainer John Fulton has died, aged 69, at his Bunyip property.

Racing Victoria confirmed Fulton died on Tuesday while working with a horse but the circumstances of his death were not clear.

Fulton held a trainer's licence in Victoria for 34 years.

His last winner came at Pakenham in May when Time For Dancing won a maiden.

Fulton was also committee member of the Pakenham Trainers' Association.

"John was a hard working trainer, who was passionate about his horses and made a valuable contribution to the Victorian racing industry over more than three decades," RV chief executive Bernard Saundry said.
