Jackson, 65, died Monday of a heart attack.
Former President Bill Clinton delivered a heartfelt eulogy, said Atlanta television station WXIA.
"I loved Maynard Jackson," Clinton said. "I loved every talk I ever had with him. I loved every argument I ever had with him. I loved him when he was reprimanding me and when he was praising me. I loved him because his heart was good."
The Rev. Vincent Guy of Friendship Baptist Church led the funeral service at Boisfeuillet Jones Atlanta Civic Center.
In closing, Clinton said, "...You saved your very best crowd until last. God bless you, friend."
