The 2018–19, UAE Pro League was the 45th edition with Al Ain being the defending champions after winning their 13th title. Both Baniyas and Kalba returned to the pro league after getting relegated back at 2017. After losing Al Shabab and Dubai last season the league has been reduced to 12 teams. Both the teams needed to get back to 14 teams so they held a relegation play off between bottom two teams of last year and the 3rd and 4th placed teams of the 2nd division. Sharjah set a record of the longest unbeaten run in a UAE Pro League season for 23 games before losing to Al Wasl 3–2. In 2019, Sharjah won their first title since 1996 after beating Al Wahda 3–2, this was the first time a team outside of Dubai and Abu Dhabi won the league since the 1996. On 26 May, Emirates and Dibba Al Fujairah were relegated after a fixed match between Shabab Al Ahli and Fujairah favored Fujairah and got them out of relegation. The Emirates demanded that the UAEFA investigate on the match between Shabab Al Ahli and Fujairah, questioning the legitimacy of the two penalties that was rewarded to Fujairah and the two goals that was disallowed for Shabab Al Ahli.[1] However the UAE court later rejected their complaint and the team got relegated[2]
