士多啤梨（strawberry），又寫士多罷厘，亦叫草莓，係生果一種，品種廿幾個。

喺分類學上面，士多啤梨係草莓屬（Fragaria L），歸被子植物門（Angiospermae）薔薇亞綱（Rosidae）薔薇亞科（Rosoideae）。

分類

There are more than 20 different Fragaria species worldwide. Key to the classification of strawberry species is recognizing that they vary in the number of chromosomes. There are seven basic types of chromosomes that they all have in common. However, they exhibit different polyploidy. Some species are diploid, having two sets of the seven chromosomes (14 chromosomes total). Others are tetraploid (four sets, 28 chromosomes total), hexaploid (six sets, 42 chromosomes total), octoploid (eight sets, 56 chromosomes total), or decaploid (ten sets, 70 chromosomes total).

As a rough rule (with exceptions), strawberry species with more chromosomes tend to be more robust and produce larger plants with larger berries (Darrow).

Diploid species

• Fragaria daltoniana
• Fragaria iinumae
• Fragaria nilgerrensis
• Fragaria nipponica
• Fragaria nubicola

Octoploid species and hybrids

• Fragaria x ananassa (Garden Strawberry)

Decaploid species and hybrids

Numerous other species have been proposed. Some are now recognized as subspecies of one of the above species (see GRIN taxonomy database).

The Mock Strawberry and Barren Strawberry, which both bear resemblance to Fragaria, are closely related species in the genus Potentilla. The Strawberry tree is an unrelated species.
