The 1888 Louisiana hurricane was a major hurricane that caused significant flooding and wind damage to the Mississippi River Delta and the Mississippi Valley in late August 1888. It was the third tropical cyclone and second hurricane of the 1888 Atlantic hurricane season. The cyclone first appeared north-northeast of the Turks and Caicos Islands, but may have formed earlier, undetected. It moved west-northwest, reaching hurricane intensity and making several landfalls in the Bahamas. In the island chain, the hurricane caused some damage to shipping, fruit groves, and fences, but apparently caused no known deaths.
