Daniel Jimeno Romero, a 27-year-old from Madrid, was gored to death during the annual running of the bulls in Pamplona and nine others were injured in what became the bloodiest run in decades.
Mr Romero died after a bull's horn pierced his neck and lungs during the half mile sprint through the cobbled streets of the northern Spanish town.
He is the first man to be gored to death during the run for 14 years.
He was brought down by a 1,130 lb (515 KG) brown beast named Capuchino which became disorientated and aggressive after separating from the pack of bulls.
Each morning at 8 o'clock during the eight-day fiesta six fighting bulls are released to stampede through the winding streets to the bullring.
Fuelled by alcohol during what has become one of Europe's biggest street parties, participants test their bravado and sprint alongside the bulls while attempting to dodge their horns.
Friday's run, the fourth of this year's San Fermin festival was described as the bloodiest in decades and raised the death toll to 15 since record-keeping began in 1911.
Mr Romero was treated at the local hospital but surgeons were unable to save him and he was pronounced dead at 8.45 am.
"He suffered mortal injuries, so there was nothing we could do to save his life," said Esther Vila, the surgeon who operated on him."He had lost a great deal of blood."
Another six people were being treated for injuries, said a spokesman at the Virgen del Camino hospital in Pamplona.
Among them was a 61-year-old American man who was said to be in a serious condition in intensive care having suffered head injuries.
Another American man in his sixties suffered a fractured elbow and a 20 year-old British man was reportedly being treated for minor injuries.
An Australian, an American, a Scottish man and a Swiss national were injured in other runs this week.
The last fatality occurred in 2003, when local man Fermin Etxberri, 63, was trampled to death. Friday's death was the first fatal goring since that of American Matthew Tassio in 1995.
Baby jumping is a traditional Spanish practice dating back to 1620 that takes place annually to celebrate the Catholic feast of Corpus Christi in the village of Castrillo de Murcia near Burgos. During the act - known as El Salto del Colacho (the devil's jump) or simply El Colacho – men dressed as the Devil (know as the Colacho) jump over babies born during the previous twelve months of the year who lie on mattresses in the street. The festival has been rated as one of the most dangerous in the world.
The origins of the tradition are unknown but it is said to cleanse the babies of original sin, ensure them safe passage through life and guard against illness and evil spirits. Check out these scary pictures
I'm sure this old man will fall and step on babies as I see in the picture, he is now in the middle of the mattress but cant move further...haha..just kid
it's pity that they dont record the moment the men jump over the babies, will be more thrilling than looking at the pics though
