Cornelis Jacobus Snijders (29 September 1852 - 26 May 1939) was a Dutch military leader. He was Commander-in-Chief of the Armed Forces of the Armed Forces of the Netherlands during World War I.
In 1869 Snijders joined the Royal Military Academy in Breda, becoming an engineer. In 1873 he went to the Dutch East Indies, and fought in the Aceh War.
In October 1875 Snijders was back in the Netherlands. He was again placed with the Engineers. Here, he had an important role in the design and construction of the armored fortresses of IJmuiden, Hoek van Holland, and Fort Harssens. From 1882 to 1886 he was in Magdeburg to oversee construction of the armored cupolas. Snijders also attended related trials in Italy and Romania.
On 1 July 1910, Snijders was made chief of the general staff. He was a proponent of military aviation. In 1913, Snijders created the Aviation Department. Later the navy received an airforce as well. Snijders was also First Chairman of the Dutch Association for Aviation.
When tensions grew in anticipation of World War I, Snijders was made Commander-in-Chief of the Armed Forces. Shortly afterward, he was promoted to full general.
In April 1918, one month after the signing of the Treaty of Brest-Litovsk, which freed Germany on its Eastern Front, he opposed war with Germany, making clear that if war was to be fought, he preferred to fight alongside Germany.
