Axel Nilsson Ryning, born 1552, died 8 January 1620, was a Swedish Lord High Admiral, Marshal, Councilor, and Baron to Tuna farm in Österåker parish in the current Österåker municipality in Österskär in Åkersberga, Stockholm county.
His activities began immediately after the death of Johan III, when he was appointed to Duke Charles' council in 1592 and in the same year mediated reconciliation between the duke and the six councilors, who in 1590 were arrested for forging stamps.
On his departure in 1594, Sigismund appointed Erik Brahe, who was a Catholic, as governor of Stockholm.
In 1599, Erik Brahe was replaced by Axel Ryning and Carl Sture.
Gustaf II Adolf rewarded Ryning's accomplishments by elevating him to Marshal and Lagman which was recorded in Södermanland's 1611 law saga.
