Tropical Depression Four was a tropical depression during the 2000 Atlantic hurricane season that did not reach tropical storm status. It was an unusually small depression, and it had limited circulation. It formed about 400 miles east of Cape Canaveral, Florida on August 8. It dissipated on August 11.
The depression caused no damage and no fatalities.

Tropical Depression Four was an unusually small tropical depression with limited convection that formed about 400 miles east of Cape Canaveral, Florida on August 8. The precursor disturbance to the depression was a low that had detached from a frontal boundary in the central subtropical Atlantic Ocean on August 4. The low moved southwestward over the next few days, and on August 8, hurricane hunter aircraft found a well-defined surface circulation with minimal convection. Based on this, the system was upgraded to Tropical Depression Four. After forming, the depression moved westward with no change in strength for the next two days. On August 10, the depression was about 70 miles east of Cape Canaveral, Florida when it abruptly turned northeast in response to an approaching deep-layer trough over the eastern United States. On August 11, the depression dissipated.
A reconnaissance wind report at 1500 ft of 47 kt could be used to argue that the depression attained tropical storm status. However, the (surface-adjusted) tropical storm force winds were reported during only one pass through the system and covered an area less than 10 nautical miles across. These winds are judged to have been unrepresentative of the system's maximum sustained wind and so the cyclone has not been designated as a tropical storm.
