To mark the anniversary of the Bataclan terror attacks, François Hollande took part in a ceremony of the stadium, north of Paris, where the first of the 130 victims was killed.
The French president unveiled the plaque at door D of the stadium in Saint-Denis to commemorate Manuel Dias, who was killed in the suicide bomber attack.
There was a minute's silence and a wreath was laid, while Dias' son made a short speech calling for "tolerance" and "intelligence", according to RTBF TV.
Michael Dias said his Portuguese-born father was "proof that integration is possible [and] necessary" to fight against intolerance. He added: "Long live tolerance, long live intelligence, long live France."
Manuel Dias, 63, died outside the national stadium where France were playing against Germany in a football match during the first attack in Paris on 13 November 2015, in which 130 people died.
France captain Hugo Lloris told reporters: "We the players and all those who were in the stadium that day, we are all linked by this tragedy.
"It's a tragic event but as we use to say, we have to look forward and try to turn the page, even if this event will be engraved in our memories."
Hollande told French TV on Saturday, 12 November: "We have to remember. One year ago, almost to the day, we were here for a friendly game and three bombs were detonated, with one man being killed.
"We have to remember there were 130 people who died and hundreds of others who were injured. For them and for those who survived we must remember."
The French president and Anne Hidalgo, the Paris mayor, also went on to unveil plaques at restaurants and bars in the area where gunmen who swore allegiance to Islamic State (Isis) fired into the crowds on a Friday evening.
Hollande and Hidalgo were joined by Prime Minister Manuel Valls and Interior Minister Bernard Cazeneuve at a memorial ceremony near Bonne Biere, which was targeted in the terrorist attacks, which were the worst extremist violence to hit France, according to abc news.
At the Bataclan concert hall, the names of the victims were read out, followed by a moment of silence in honour of those who perished in the attack.
