James Laidlaw Huggan (died on 16 September 1914, aged 25) was a Scotland rugby union player. He was killed in World War I at the First Battle of the Aisne. He died two days after Ronald Simson, another Scottish player, who was the first rugby international to die in the conflict, and who was also at the Aisne.
Huggan played for London Scottish RFC, and had taken part in the last rugby international before the war, the Calcutta Cup match at Inverleith (Edinburgh) in March 1914. He scored three tries in that match.
