He taught English at the university.
Boalia police station OC Shahdat Hossain said unidentified miscreants hacked him with sharp weapons and left him to die at the Battala Crossing in Salbagan area around 7.30am.
The motive behind the murder is not immediately known.
Two years ago, another Rajshahi University teacher AKM Shafiul Islam was similarly murdered.
Though his murder was initially claimed by Islamist radicals, police later ruled out that possibility. Police said he was murdered as a sequel to personal rivalry.
But some years ago, two more professors of the Rajshahi University had been killed.
