Harris, 32, had a seemingly rough year in terms of his personal life - he split up from his girlfriend of 15 months, Taylor Swift, earlier this month, just days after being injured in a nasty car accident.
But it hasn't affected his earning power, with the Scottish-born DJ raking in an estimated USD 63 million.
The list analyses earnings from record sales and live performances, as well as sponsorship deals, endorsements and other such ancillary contracts.
Following him on the list are Dutch-born Tiesto in second place, who raked in USD 38 million for the year, and Frenchman David Guetta in third.

Guetta soundtracked the Euro 2016 football tournament, as well as penning a multi-million dollar deal with 7-UP.
The top ten names on the list are all male artists, and combined earned USD 270.5 million from June 2015 to June 2016 - but the figure is 1 per cent down on the previous year, the first time that such earnings have been less than they were before since Forbes started compiling the list in 2012.
Newcomers Dimitri Vegas & Like Mike are the only new names in the list, edging in at No.10 with USD 15.5 million, and behind such established names as Skrillex and Martin Garrix.
