Houma is the home to the second largest Mardi Gras celebration outside of New Orleans. All the festivities get under way two weekends before Mardi Gras day. The parade and krewes in all their pageantry run along Main Street. Zydeco music fills the air. Cajun food and crawfish are bountiful and general high merriment and good times soar.

Throughout the year, there are numerous other fairs and parades, including the Irish-Italian parade, the Terrebonne Livestock and Agricultural Fair and Rodeo, the T-Cailliou Lions Club Fishing Rodeo and a Christmas festival that features the arrival of Papa Noel in Houma. A full calendar of events is available from the Houma Area Convention and Visitors Bureau by calling 800-688-2732.

A rich Native American tradition continues to maintain a strong presence in this area. Two energy-filled pow-wows take place during the year: the Calling of the Tribes and the Grand Bois Intertribal. Both colorful events feature Native American crafts, food and dances.
