More than a dozen Leeds United fans were arrested at matches over a four-year period from 2014/15 to 2017-18 - with Manchester United the only club to have had more arrests in the same timeframe.
15 Leeds supporters were involved in football-related arrests where racism was an aggravating factor or a feature.
Manchester United had almost twice that number, with 27 arrests involving their fans. 15 Millwall supporters were also arrested over the same four-year period - the same number as Leeds.
A spokesperson for the Whites said that racism 'will not be tolerated by the club', but pointed to the fact that the number of arrests was a tiny percentage of the overall attendance at Elland Road and a small number of those who travel to away matches, where support is often larger than other Championship clubs.
Leeds took 4,000 away supporters to seven matches last year, including 7,000 to Blackburn Rovers.
The figures have been released by the Press Association under a Freedom of Information request and take into account every single racism-related incident where an arrest has been made.
Where racism has been recorded as a feature of an incident, it requires the arresting officer to tick a box, which is why the Home Office says the overall accuracy of the data cannot be guaranteed.
National figures for the 2018/19 season are due to be released later this summer.
Anti-discrimination body Kick It Out said last November that there were 520 reports of discriminatory abuse during the 2017-18 season, an 11 per cent increase on the previous campaign and the sixth year in a row where the figure had risen.
Fifty-three per cent of those reports concerned alleged racist abuse.
A statement from Kick It Out read: "These figures show racism is a nationwide problem shared by clubs of all different sizes in all parts of the country.
"We support them in challenging racism and other forms of discrimination, and will continue our programme of education in the game to help reduce this problem."
The full list of all football league clubs where 10 or more arrests were made is as follows:
- Manchester United - 27
- Leeds United - 15
