Lobelia is a genus of flowering plants comprising 415 species, with a sub cosmopolitan distribution primarily in tropical to warm temperate regions of the world, a few species extending into cooler temperate regions. They are known generally as lobelias.

The genus Lobelia comprises a substantial number of large and small annual, perennial and shrubby species, hardy and tender, from a variety of habitats, in a range of colours. Many species appear totally dissimilar from each other. However, all have simple, alternate leaves and two-lipped tubular flowers, each with five lobes.

Flowering is often abundant and the flower colour intense, hence their popularity as ornamental garden subjects. Several species are cultivated as ornamental plants in gardens.

The species used most commonly in modern herbalism is Lobelia inflata (Indian tobacco). Use of lobelia for cardiovascular diseases may cause adverse effects.
