The Wellesley Police and Fire Departments responded to the scene, along with paramedics and dive teams from the Natick, Cambridge and Westborough fire departments.
The woman was able to get to the shore near Standwish Circle, police said.
Trained divers conducted an underwater search for the man and located him around 5:20 p.m. approximately 10 yards off shore under water, police said. He was unconscious and unresponsive, police said.
The man was taken by boat to Oakland Street and then taken by ambulance to Newton Wellesley Hospital where he was pronounced dead.
"It's unexpected, it's unsettling and it really disrupts the calm nature of the pond area as we enjoy today," witness Richard Teneyck said.
The victim's name is not being released until his family has been notified.
The fatal drowning is under investigation but does not appear to be suspicious, police said.
Police asked people to avoid the area of Oakland Street, Standish Road and Longfellow Pond as they conducted their search Monday evening.
