The 2017 Atlantic hurricane season is a future event in the annual formation of tropical cyclones in the Northern Hemisphere. The season will officially begin on June 1, 2017, and end on November 30, 2017. These dates historically describe the period each year when most tropical cyclones form in the Atlantic basin and are adopted by convention. However, the formation of tropical cyclones is possible at any time of the year.

Ahead of and during the season, several national meteorological services and scientific agencies forecast how many named storms, hurricanes and major (Category 3 or higher on the Saffir-Simpson scale) hurricanes will form during a season and/or how many tropical cyclones will affect a particular country. These agencies include the Tropical Storm Risk (TSR) Consortium of the University College London, the National Oceanic and Atmospheric Administration (NOAA) and Colorado State University (CSU). The forecasts include weekly and monthly changes in significant factors that help determine the number of tropical storms, hurricanes, and major hurricanes within a particular year.[2] Some of these forecasts also take into consideration what happened in previous seasons and the dissipation of the 2014–16 El Niño event. On average, an Atlantic hurricane season between 1981 and 2010 contained twelve tropical storms, six hurricanes, and two major hurricanes, with an Accumulated Cyclone Energy (ACE) index of between 66 and 103 units.[1]
The first forecast for the year was issued by TSR on December 13, 2016.[2] They anticipated that the 2017 season would be a near-average season, with a prediction of 14 named storms, 6 hurricanes, and 3 major hurricanes. They also predicted an ACE index of around 101 units.[2] On December 14, CSU released a qualitative discussion detailing five possible scenarios for the 2017 season, taking into account the state of the Atlantic Multidecadal Oscillation and the possibility of El Niño developing during the season. [3]
Storm names
The following list of names will be used for named storms that form in the North Atlantic in 2017. Retired names, if any, will be announced by the World Meteorological Organization in the spring of 2018. The names not retired from this list will be used again in the 2023 season.[4] This is the same list used in the 2011 season, with the exception of the name Irma, which replaced Irene.

Season effects
This is a table of all the storms that have formed in the 2017 Atlantic hurricane season. It includes their duration, names, landfall(s), denoted in parentheses, damages, and death totals. Deaths in parentheses are additional and indirect (an example of an indirect death would be a traffic accident), but were still related to that storm. Damage and deaths include totals while the storm was extratropical, a wave, or a low, and all the damage figures are in 2017 USD.
