Al Ahly, who have previously won Africa's foremost club competition in 1982, 1987, 2001, 2005, 2006, 2008 and 2012, won 3-1 on aggregate on Sunday night after a 1-1 stalemate in the first leg.
The Red Devils of Cairo pocketed the cash prize of $1.5-million and will also represent Africa at the Fifa Club World Cup in Morocco next month.
"I'm very happy we won. It was a difficult game and a good test for us," said Al Ahly coach Mohamed Youssef.
"Orlando Pirates are a strong side having eliminated Esperance and TP Mazembe on their journey to the final. We were focused on creating chances and capitalising on the mistakes of our opponents."
Pirates coach Roger De Sa admitted the Egyptians had been the better side over the two legs.
"Their experience showed in the game. We knew it was going to be difficult. We lost the tie when the first leg ended 1-1. Nevertheless, we played well and created some chances," he said.
"I'm very disappointed because I believed we could have achieved it but I'm very happy though with the way we carried ourselves."
Taking opportunities
Mohamed Aboutrika opened the scoring in the 54th minute when he stabbed home from just outside the six-yard box.
Ahmed Abdul Zaher doubled the Ahly lead in the 78th minute when, unmarked inside the box, he shot past the Pirates goalkeeper Senzo Meyiwa.
The Egyptian champions were reduced to 10 men six minutes from the time when defender Sherif Abdel Fadil was sent off for a foul on Daine Klate.
Pirates, champions in 1995, put up a spirited fight but Ahly's second goal seemed to make them lose heart inside a packed Arab Contractors Stadium in Cairo.
The South African champions created several chances, but could not take them.
The best chance of the first half fell to the Buccaneers in the 35th minute. Tlou Segolela somehow failed to convert from inside the six-yard box, after a superb pull-back by Klate from the right with the Al Ahly goalkeeper well beaten.
Pirates failed again in front of goal in the 63rd minute when Lennox Bacela dribbled past goalkeeper Sherif Ekramy, but his final ball screamed across the face of goal after the Al Ahly keeper forced him wide.
Lasers
Sports Minister Fikile Mbalula condemned the behaviour of Egyptian fans who shone green lasers into the eyes of Pirates players.
During an interview with Eyewitness News, the minister called on Africa's football governing body to take action: "I think that behaviour must be condemned in the strongest terms," she said.
It follows earlier clashes between Al Ahly supporters and police before the match as fans threw rocks and tried to force their way in to the stadium to watch the game. – Sapa
