'''''Nicotiana longiflora''''', the '''longflower tobacco'''<ref>{{PLANTS|id=NILO|taxon=Nicotiana longiflora|accessdate=29 January 2016}}</ref> or '''long-flowered tobacco''',<ref name=BSBI07>{{BSBI 2007 |access-date=2014-10-17}}</ref> is a species of [[tobacco]] native to [[South America]] that is sometimes cultivated for its tubular [[flower]]s that emit a very sweet odour at night.

This plant has been a significant source of disease resistance in flue-cured and [[Burley (tobacco)|burley tobacco]]. Some of the disease impacted by resistance from this species are: [[black shank]], [[Heterodera|cyst nematode]], [[root-knot nematode]], and wildfire. The resistance form ''N. longiflora'' imparts near immunity to race 0 black shank, but no resistance to race 1. One of the varieties still in use today is 14 x L8, the second most popular [[burley tobacco]] variety in the [[United States|U.S.]]
