The Ninth Ward or 9th Ward is a distinctive region of New Orleans
Among the famous past and present residents of the 9th Ward are Fats Domino, rapper Brian "Baby" Williams, former Washington Husky and NBA basketball player Eldridge Recasner, and Magic—"Mr. Ninth Ward".
Hot Boys music video "We On Fire", which was partly filmed there. Since then, it has become commonplace for many artists to mention the Ninth Ward in their songs.
Too Short in 'Just Another Day' shouts out to Ninth Ward, as well as many other artists.
Might not be where they originally got their name from. But the district of 9th ward is real prominent in rap.
