盧文氏樹蛙，是一種長度平均為1.5厘米至2厘米的小青蛙，它是香港最小的兩棲動物。
盧文氏樹蛙為香港獨有的品種，僅在南丫島丶大嶼山丶赤鱲角和蒲台島有出沒記錄。由於興建新的香港機場的關係，盧文氏樹蛙在赤鱲角的棲息經已消失。
根據盧文氏樹蛙的生態學研究，盧文氏樹蛙會在沒有魚類丶貧瘠丶陰涼丶靜止或緩慢流動的水域中繁殖，並於地點森林或灌木叢中棲息

Romer's Tree Frog, Philautus romeri, is a tiny frog with an average length of 1.5 cm to 2 cm. It is Hong Kong's smallest amphibian. The frog is endemic to Hong Kong and has only been recorded from a few locations in Hong Kong, namely, Lamma Lantau, Chek Lap Kok, and Po Toi. The habitat of Romer's Tree Frog at Chek Lap Kok was lost due to the construction of the new Hong Kong airport.
During a five-year survey of Hong Kong amphibians, the Ngong Ping valley is found to support the largest population of Romer's Tree Frog. Most of other Romer's Tree Frog habitats on Lantau are in the lowlands or basins outside the two country parks and are thererfore vulnerable, the subject site lies at an altitude of above 400mPD.
According to a study of the ecology of Romer's Tree Frog, this species breeds in fishless, oligotrophic, shaded, still or slow-flowing waters. The breeding sites are usually associated with forest or shrubland whereas the non-breeding habitats are mostly found in the forest, plantations and clearings within them.
