Giovanni Narcissus Hakkenberg (6 December 1923 – 15 February 2013) was a Dutch marine of Indonesian and European descent, and decorated war hero and knight of the Military Order of William.

The Military William Order is the highest honour in the Netherlands, bestowed for "performing excellent acts of Bravery, Leadership and Loyalty in battle".

Hakkenberg was an energetic mission leader or solo combatant involved in many crucial tactical actions mostly carried out at night and alone or with a small detachment.

[3] The Royal Decree no.40 of 6 March 1951 stated: ...distinguished in battle by great acts of courage, and loyalty as commander of a detachment of the Marine brigade from September 1947 to May 1949 in the fight against terrorist gangs (and TNI units) in East Java, where he was head of only a very small group – sometimes not more than three to five men.

Hakkenberg lived in a care home in Wageningen and died during the afternoon of Friday 15 February 2013 in De Gelderse Vallei hospital in Ede, Netherlands.
