True Blue King Box is an American cigarette brand manufactured by R.J. Reynolds Tobacco Company, a subsidiary of Reynolds American. Originally introduced by Lorillard Tobacco Company in September 1966, the True brand was acquired by Reynolds American in 2015.

True cigarettes are distinguished by their recessed filter design, which features a plastic piece that prevents the top of the cigarette from being broken, torn, or crushed. The Blue variety offers a non-menthol flavor profile in a King size format packaged in a hard flip-top box.

Sold at Costco in a carton format containing multiple packs of 20 cigarettes each.
