The 2001 Atlantic hurricane season was an above-average Atlantic hurricane season in which fifteen named storms formed. The season officially began on June 1 and ended on November 30, dates that conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. The season's first tropical cyclone, Tropical Storm Allison, formed on June 5 while the season's final system, Hurricane Olga, dissipated on December 6. The season produced seventeen tropical depressions, of which fifteen intensified into tropical storms, nine became hurricanes, and four strengthened into major hurricanes.

This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, and dissipations during the season. It includes information that was not released throughout the season, meaning that data from post-storm reviews by the National Hurricane Center, such as a storm that was not initially warned upon, has been included.

The time stamp for each event is first stated using Coordinated Universal Time (UTC), the 24-hour clock where 00:00 = midnight UTC. The NHC uses both UTC and the time zone where the center of the tropical cyclone is currently located. The time zones utilized (east to west) prior to 2020 were: Atlantic, Eastern, and Central. In this timeline, the respective area time is included in parentheses. Additionally, figures for maximum sustained winds and position estimates are rounded to the nearest 5 units (miles, or kilometers), following National Hurricane Center practice. Direct wind observations are rounded to the nearest whole number. Atmospheric pressures are listed to the nearest millibar and nearest hundredth of an inch of mercury. __TOC__
