Hurricane on the Bayou is an American 2006 documentary film that focuses on the wetlands of Louisiana before and after Hurricane Katrina.

Hurricane on the Bayou is both a documentary of Hurricane Katrina's effects and a call to restore Louisiana's wetlands, rebuild New Orleans, and honor the culture of the city. The film is narrated by actress Meryl Streep and driven by a jazz-, blues-, Cajun-, and gospel-fueled soundtrack featuring Tab Benoit, Amanda Shaw, Mavis Staples, and Allen Toussaint.

It was originally a "what-if" scenario about a major hurricane impacting New Orleans – prior to Hurricane Katrina. The film debuted at the Entergy IMAX in New Orleans, on the one-year anniversary of Hurricane Katrina, several months before being shown elsewhere.
