The 1887 Atlantic hurricane season was the most active Atlantic hurricane season on record at the time in terms of the number of known tropical storms that had formed, with 19. This total has since been equaled or surpassed multiple times. The 1887 season featured five off-season storms, with tropical activity occurring as early as May, and as late as December. Eleven of the season's storms attained hurricane status, while two of those became major hurricanes.^{[nb 1]} It is also worthy of note that the volume of recorded activity was documented largely without the benefit of modern technology.^[2] Consequently, tropical cyclones during this era that did not approach populated areas or shipping lanes, especially if they were relatively weak and of short duration, may have remained undetected. Thus, historical data on tropical cyclones from this period may not be comprehensive, with an undercount bias of zero to four per year between 1886 and 1910 estimated.^[3] The first system was initially observed on May 15 near Bermuda, while the final storm dissipated on December 12 over Costa Rica.

Of the known 1887 cyclones, the first and third were first documented in 1996 by José Fernández-Partagás and Henry F. Diaz. They also proposed large alterations to the known tracks of several of the other 1887 storms. Later, while the Atlantic hurricane reanalysis project did not add or remove any cyclones from the official hurricane database (HURDAT), the group lengthened the tracks of the sixth and fifteen storms and upgraded the latter to a hurricane. In 2014, climate researcher Michael Chenoweth's reanalysis study recommended the removal of three storms and the addition of eight new systems to HURDAT, for a total of 24 cyclones in the 1887 season.

Only a few of the storms during the 1887 season did not impact land. The fourth system caused one death and more than $1.5 million (1887 USD) in damage,^{[nb 2]} mostly due to flooding in the Southeastern United States. Later, the sixth, seventh, and eighth storms caused two, more than one, and seven fatalities, respectively, nearly all offshore Newfoundland, while the sixth and seventh cyclones inflicted some damage in the Bahamas and North Carolina. Next, the ninth system drowned 14 sailors and caused significant impacts over southern Texas and northeastern Mexico. In October, at least $10,000 in damage occurred in Louisiana due to the thirteenth storm, while the sixteenth cyclone inflicted at least $7,000 in damage after sinking a ship and drowned two people after another vessel capsized. The season's nineteenth and final system resulted in 15 deaths across the Caribbean Sea.
