Horn made his professional debut in Melbourne on 1 March 2013, winning by second-round technical knockout. In just his seventh pro bout he outpointed two-time world title challenger and former IBF #1 contender Naoufel Ben Rabah. On 27 April 2016, Horn faced former two-division world champion Randall Bailey. After dropping Bailey in the second round, Horn was knocked down in the third round. Horn won by TKO after Bailey refused to get up from his corner before round eight. On 21 October 2016, Horn fought Rico Mueller and defeated the German by TKO in round nine. After the fight, the WBO ranked him the #2 welterweight in the world. On 10 December 2016, Horn faced former IBO welterweight champion Ali Funeka, whom he stopped in the sixth round. With Top Rank promoter Bob Arum in attendance, his win set up a potential showdown with eight-division world champion Manny Pacquiao.

Horn signed up to face WBO welterweight champion Manny Pacquiao in Brisbane on 23 April 2017.[4] The announcement of the fight was met with relative surprise and disappointment due to Horn's limited exposure on the world stage, which led Pacquiao to comment "I don't know who Jeff Horn is". A tweet on 12 February by Pacquiao complicated negotiations when he said that he planned to fight in the United Arab Emirates. On 26 February, Pacquiao and Amir Khan announced that they had reached an agreement to fight, leaving Horn without an opponent. On 7 March the fight with Khan was called off and on 5 April a deal for the Pacquiao–Horn fight was reached. A press conference on 10 April signaled confirmation of the fight, which took place at Suncorp Stadium on 2 July 2017. Horn defeated Pacquiao via unanimous decision after 12 rounds.[5] CompuBox stats showed that Pacquiao landed 182 out of 573 punches thrown (32%), whilst Horn landed only 92 of 625 thrown (15%).[6][7] Many pundits, as well as many current and former boxers, believed Pacquiao had done enough to retain the WBO title.

Horn's win over Pacquiao was also criticized by some boxing analysts, sports journalists and fans alike, with some comparing the decision to that of the controversial Pacquiao vs. Timothy Bradley fight.[8][9] In regards to the controversial scorecards, ESPN's Dan Rafael scored the fight 117–111 and ESPN analyst Teddy Atlas scored it 116–111, both for Pacquiao.[10] The Guardian and the International Business Times both scored the fight in Pacquiao's favor as well, 117–111.[11][12] BoxingScene had it 116–112 for Pacquiao, while CBS Sports scored the fight 114–114 even.[13][14] BoxNation's Steve Bunce scored the fight 115–113 for Horn.[15] In total, 12 of 15 media outlets scored the bout for Pacquiao, 2 of 15 outlets ruled in favor of Horn and 1 scored a draw.[16]

Pacquiao claimed Horn got away with numerous dirty tactics in the fight, using illegal blows including elbows and headbutts.[17]

In response to a formal request by the Philippine Games and Amusements Board, the WBO agreed to review the fight between Pacquiao and Horn. It was scored round-by-round by five anonymous judges, but the WBO stated that they do not have the power to reverse the original result of the fight.[18] The WBO rescored the fight in favor of Horn winning seven rounds and Pacquiao winning five.[19]

Initially, Horn was to give Pacquiao a rematch, but the rematch was delayed and did not eventuate. As a result, Horn instead made a voluntary defence of the WBO title against Gary Corcoran on 13 December 2017. Corcoran's corner decided to throw in the towel in the eleventh round, thus Horn retained the title via TKO. Both fighters were cut during the fight, but Horn was leading on the scorecards at the time of the stoppage.

Horn was challenged by Terence Crawford on 9 June 2018, for the WBO welterweight title. Crawford defeated Horn via technical knockout in the ninth round, becoming the new WBO welterweight champion.[20]

Horn moved up to middleweight after the loss to Crawford and faced Anthony Mundine on 30 November 2018. He defeated Mundine in just 96 seconds.[21]

Next, Horn faced Michael Zerafa on 31 August 2019 in Bendigo. For the second time in his career, Horn lost via technical knockout in the ninth round.[22]

Horn however won the rematch on 18 December 2019 by majority decision to bring his record to 20–2–1.[23]

On 26 August, 2020, Horn faced one of Australia's best up-and-coming fighters Tim Tszyu. Tszyu was ranked #5 by the WBO at super welterweight.[24] Tszyu dropped Horn twice, once in the third and once in the sixth round, and continued to dominate Horn until the end of the eighth round, when Horn's corner decided not to continue the fight.[25]

On 2 July 2023, Horn announced his retirement, so he could undertake his role as an ambassador for an anti-bullying foundation. He stated that he had passed up offers of $1 million to return to the ring after his August 2020 loss to Tim Tyszu.[26]
