The 1994 Grand National (officially known as the Martell Grand National for sponsorship reasons) was the 147th official renewal of the Grand National horse race that took place at Aintree near Liverpool, England, on 9 April 1994.

It was won in a time of 10 minutes 18.8 seconds, and by a distance of lengths by 16/1 shot Miinnehoma, ridden by Northern Irish jockey Richard Dunwoody, his second Grand National victory. The winner was trained by Martin Pipe of Wellington, Somerset, and carried the red jacket with yellow star and sleeves and cap with red star of comedian Freddie Starr. The winning owner collected £115,606 of a total prize fund shared through the first five finishers of £194,000 (none of which was carried over from the aborted 1993 race). A maximum of 40 competitors were permitted but only 36 ran. All of the horses returned safely.

Leading contenders

Moorcroft Boy was installed as favourite on race day after an impressive season which had seen him finish first or second in nine consecutive long-distance chases, including a victory in the Warwick National in January and a second place to Master Oats in the Greenhalls Gold Cup at Kempton in February. This impressive run and very lenient treatment from the handicapper, who allotted him nine stone and 8 lbs and ensured he would not be giving weight to any of his rivals, led the public to back him down to 5/1 at the off. Adrian Maguire who had partnered him in the most recent four of those nine outings took the mount as his second ride in the National, having also been part of the previous year's void race. Maguire was also the leading rider at the meeting with three wins going into the National, although he had been handed a three-day riding ban after the first race of the day for over use of the whip. The ban would not take effect at the Aintree meeting however.

Maguire kept the horse out of trouble in mid-division for most of the race before gradually moving through the fallers and tiring horses to lie fifth at the second jump of Becher's Brook. The favourite moved up to join the three leaders turning for home and jumped the second-last disputing the lead with Miinnehoma. When Maguire asked the horse to quicken into the last fence he jumped two lengths clear, but weakened on the 494-yard run-in to finish 21 lengths back in third. After the race it emerged that Moorcroft Boy had broken a blood vessel within strides of the last fence and raced up the run-in choking. He later suffered a broken neck when falling in the Becher Chase the following November but was nursed back to health to win the 1996 Scottish Grand National, his final race before retiring.

Double Silk was another hunter chaser who went to Aintree on the back of a run of ten consecutive victories, which included the 1993 Cheltenham and Aintree Foxhunters chases, the former of which had seen him secure a second consecutive victory over Moorcroft Boy. The remainder of his wins had been in small hunter chases before returning to Cheltenham three weeks before the National to successfully defend his Foxhunters title. Like the favourite, he was lightly treated by the handicapper, carrying ten stone and 4 lbs, and was heavily backed down to a starting price of 6/1 at the off. Amateur rider Ron Treloggan, who had partnered the horse in all of his previous fourteen starts, became one of nine riders making their Grand National debut, including future winning riders, Paul Carberry and Tony Dobbin. Double Silk was sent to the front right at the start and stayed there until the 13th fence when, for the only time in a career that spanned 31 races, he fell, having possibly been unsighted by a loose horse. Neither horse nor rider took part in the National again.

Master Oats was backed heavily after beating Moorcroft Boy in the Greenhall's Gold cup at Kempton in February and was sent off at 9/1, giving Norman Williamson his fourth ride in the race. The pair were moving up into the front rank when they fell at the 13th fence. The horse went on to win his next five races including the Welsh Grand National and Cheltenham Gold Cup.
