Wightia is a genus of flowering plants tentatively sister to the Phrymaceae which currently contains only two species.

It grows as a tree, or a hemiepiphytic pseudo-vine, up to 15 metres (49 ft) tall.

[2] It is found in South Asia and South East Asia, from Nepal and India to Thailand, Vietnam and China's Yunnan Province, at altitudes below 2,500 m (8,200 ft).

[2] There are still morphological characters as well as nuclear genome data to support Wightia as sister to Paulownia leading it to be of proposed hybrid origin from Phrymaceae and Paulowniaceae.

[3] Due to chloroplast and mitochondrial data showing Wightia as sister to Phrymaceae it is proposed that a new family Wightiaceae be recognized.
