The 2007 World Thoroughbred Racehorse Rankings is the 2007 edition of the World Thoroughbred Racehorse Rankings. It is an assessment of racehorses which was issued by the International Federation of Horseracing Authorities (IFHA) in January 2008. It includes horses aged three or older which raced or were trained during 2007 in countries where the flat racing year runs from January 1 to December 31. These countries are generally in the Northern Hemisphere.

The ratings represent a weight value in pounds, with higher values given to horses which showed greater ability. It is judged that these weights would equalize the abilities of the horses if carried in a theoretical handicap race. The list includes all horses rated 115 or above, and it also shows the surface and the distances at which the rating was achieved.

The highest rating in the 2007 season was 131, which was given to the performance of Manduro in the Prince of Wales's Stakes. In total, 212 horses were included in the list, 32 more than in the 2006 Rankings.
