Howea forsteriana, the Kentia palm, thatch palm or palm court palm, is a species of flowering plant in the palm family, Arecaceae, endemic to Lord Howe Island in Australia. It is also widely grown on Norfolk Island. It is a relatively slow-growing palm, eventually growing up to 10 m (33 ft) tall by 6 m (20 ft) wide. Its fronds can reach 3 m (10 ft) long. The palm received the name "forsteriana" after Johann Reinhold Forster and Georg Forster, father and son, who accompanied Captain Cook as naturalists on his second voyage to the Pacific in 1772–1775.

The species is considered vulnerable by the World Conservation Union. It is cultivated on Lord Howe Island by collecting wild seeds and germinating them for export worldwide as an ornamental garden or house plant. The trade in the seeds and seedlings is tightly regulated. This plant has gained the Royal Horticultural Society's Award of Garden Merit.
