The present study is to document the diversity of alien species in the Haveri District, Karnataka in India with additional information on the habit and native range of each plant. During this study, a total of 282 alien species belonging to 225 genera in 67 families were identified and listed from various localities in the district. Of these, dicotyledons were 244 species belonging to 54 families and monocotyledons comprising 38 species come under 13 families Among the total number of alien species, 28% are native to Tropical America. Analysis of the habit shows that herbs consist of 140 species, followed by 60 trees, 57 shrubs and 25 climbers. Among 67 families, Fabaceae is the most dominant invasive family with 46 species.
