Dress Her in Indigo (1969) is the eleventh novel in the Travis McGee series by John D. MacDonald.

McGee investigates what happened to a young woman, Beatrice "Bix" Bowie, on behalf of her father, Harlan Bowie, after she disappears into the expatriate subculture of hippies and drug addicts in Oaxaca, Mexico, and is found dead.

McGee interacts with several characters to track down the true story of Bix and her four now-missing companions, Walter "Rocko" Rockland, Jerome Nesta, Mindy McLeen, and Carl Saunders.

The title phrase "Dress Her in Indigo" is found on page 244 of the first edition when one of the characters states, "Look at how splendid that color is for her.

I will dress her in indigo, and in the good blues and greens and grays."
