The number is up sharply from the 87 Saudis and foreigners executed during the whole of 2014.
In the latest case, authorities carried out the death sentence against Abdullah al-Ahmari in the southwestern region of Asir, the interior ministry said.
He had been found guilty of shooting dead another man in a dispute.
London-based Amnesty International says Saudi Arabia had the world's third-highest number of executions last year, far behind China and Iran, but ahead of Iraq and the United States.
Most Saudi executions are carried out by beheading with a sword, punishment which the interior ministry says is a deterrent.
