Haru Urara (Japanese: ハルウララ; February 27, 1996 – September 9, 2025) was a Japanese Thoroughbred racehorse who achieved a record of zero wins and 113 losses in a career spanning from 1998 to 2004. Her unbroken losing streak was covered by Japanese media in 2003, causing her to achieve national popularity as a symbol of perseverance and tenacity.

Haru Urara, a bay mare, was foaled on February 27, 1996, on Nobuta Bokujo, Utafue, Mitsuishi, Hokkaido. She was sired by Nippo Teio [ja], a top-class racehorse whose wins included the Autumn Tenno Sho and the Yasuda Kinen. Unable to find a buyer, the farm began training her as a racehorse.

At her debut on November 17, 1998, at the Kōchi Racetrack, Haru Urara lost, placing fifth –and last. Over the next four-and-a-half years, she would compete once or twice every month without winning.

In June 2003, after garnering her 80th consecutive loss, the story was picked up by the national Japanese media, making "Haru Urara" a household name. She quickly became very popular in Japan, and was called "the shining star of losers everywhere" (負け組の星, makegumi no hoshi), for continuing to run, despite her losing streak. This surge in popularity was dubbed "The Haru Urara Boom", and news about Haru Urara reached the international community.

During the boom, Haru Urara betting tickets began to be used as o-mamori, particularly for protection against traffic accidents: the word ataranai (当たらない) in Japanese can mean both "to lose a bet" and "to avoid being struck", so it was said that a Haru Urara betting ticket could protect the owner's car from being hit. In September 2003, the Kōchi Prefecture Horse Racing Association introduced a service wherein they would stamp the word on any betting ticket related to Haru Urara. O-mamori were also created from mane and tail hairs that were said to have fallen out during brushing, but production was soon halted, due to concerns expressed by animal welfare groups. They were instead replaced with wooden plaques.

At a race held on March 22, 2004, during the peak of her popularity, more than 13,000 spectators packed the Kochi Racetrack, 3,000 of whom had gathered outside before the gates opened, forcing the track to open 30 minutes earlier than scheduled. Some people waited in line for up to five hours to buy tickets at the "Haru Urara Commemorative Ticket Booth", which was established especially for the event. Fans bet a grand total of ¥121,751,200 on a Haru Urara victory, an impressive sum, particularly for a horse that had not won once in more than 100 attempts. Despite being ridden by Japan's premier jockey, Yutaka Take, Haru Urara earned her 106th consecutive loss, placing 10th among 11 horses running.

Her name means "Glorious Spring" or "Gentle Spring". Numerous products using Haru Urara's name or image have been produced, including stuffed toys, key rings, mobile phone straps, stickers, stamps, train tickets, rice, shochu, hats, T-shirts, and bras. A number of books and songs, as well as a film, were also written about Haru Urara during the boom period. The Japanese Prime Minister Junichiro Koizumi said "I'd like to see Haru Urara win, even just once. The horse is a good example of not giving up in the face of defeat."

Haru Urara ran her last race in August 2004 and retired with a record of 0 wins and 113 losses.
