The 1923 Grand National was the 82nd renewal of the Grand National horse race that took place at Aintree Racecourse near Liverpool on 23 March 1923. The race was won by Sergeant Murphy, a 13-year-old 100/6 shot ridden by Captain Tuppy Bennet and trained by George Blackwell for its owner Stephen Sanford, who collected the £5,000 prize for the winner. The 1921 winner Shaun Spadah finished in second place, with Conjuror II in third and Punt Gun fourth. Twenty-eight horses ran and all returned safely to the stables.
