Zamia angustifolia is a species of plant in the genus Zamia. It is found in the Bahamas, where it is threatened by habitat loss, and in Cuba, where it is abundant.

Z. angustifolia has dark gray to black strobili (cones) with acuminate points.{{Sfn|Ward|2016|p=172}}

It is found in the Bahamas only at two sites on coastal sand dunes on Eleuthera. A survey in the early 2010s found only 150 plants. Z. integrifolia is also found on Eleuthera, but the two species ranges do not overlap. The limited number of plants and sites, and the development of nearby areas for housing create the highest concern for conservation of the Bahamian population of the species.{{sfn|Salas-Leiva|Meerow|Calonje|Francisco-Ortega|2017|at=Methods: Collecting sites, Results: Distribution patterns}} Z. angustifolia is also found in semi-deciduous dry forests in eastern Cuba (Guantánamo, Oriente, and Santiago de Cuba provinces).{{sfnm|1a1=Meerow|1a2=Stevenson|1a3=Moynihan|1a4=Francisco-Ortega|1y=2003|1p=489|2a1=Calonje|2a2=Stevenson|2a3=Osborne|2y=2013|2p=107}} It is abundant in Cuba, but the taxonomic relationship between the Bahamian and Cuban populations needs further study.{{sfn|Salas-Leiva|Meerow|Calonje|Francisco-Ortega|2017|at=Discussion: Distribution patterns and conservation implications}}

In 1889 Gardiner and Brace listed just one Zamia species in the Bahamas, Z. angustifolia, which they referred to as "bay rush". They reported that plants of the species were harvested on Andros and New Providence islands to produce starch sold in Nassau markets.{{Cite book |last1=Gardiner |first1=John |title=Provisional List of the Plants of the Bahama Islands |last2=Brace |first2=L.
