Jaltomata werffii is a plant species endemic to the Galápagos Islands in Ecuador.

The epithet was spelled "werfii" in the original publication, but was corrected to "werffii" later, per Article 60.1 of the Code.

[1] The single "f" was a typographical error, as the plant was named in honor of Henk van der Werff.

[2][3] Jaltomata werffii is an herb up to 1 m tall.

Flowers are borne in axillary umbels of 3-4 white flowers.
