A twisted pair organizing tool is disclosed. The twisted pair organizing tool includes a body, a first and a second hole. The first and the second hole can be pressed so as to change the inner diameters thereof. When a first and a second cable are in a twisted state, the body is rotated in reverse to untwist and cause the first and a second cable to enter the first and the second hole, respectively. Once the first and the second cable have entered the first and the second hole by a predetermined length, a first end of the body is pressed such that the first and the second hole are tightly combined with the first and the second cable, and the first and the second cable are pulled out such that the first and the second cable are straightened.
