The incident occurred at Jambhalipali village, about 300 km from state capital Bhubaneswar, when 40-year-old Nata Nayak and his 35-year-old wife Surabali Nayak were asleep.
A wall, which was weakened and was in a dilapidated condition due to incessant rains for the last few days, collapsed on the couple.
Local residents took the couple to a hospital where doctors declared them dead.
The couple is survived by two daughters and a son who had a miraculous escape, police inspector N.R. Sarangi told IANS.
