Leptospermum liversidgei or lemon-scented tea tree, or lemon teatree is a shrub to 4 m found naturally growing in wet coastal heath in Eastern Australia. Leaves are 5-7 mm long, with a distinctive lemony aroma. The white or pink flowers are solitary, followed by a woody capsule.

L.liversidgei has two essential oil chemotypes:

• The citral chemotype is used as a bushfood spice to flavour teas and food products. This citral chemotype is sometimes called "lemon teatree" when the dried leaves are used in tea, and as food flavouring. Small-scale production is from wild-harvesting.
• The citronellal chemotype is cultivated as a mosquito repellent.

The shrub is also cultivated as a garden ornamental.

Leptospermum petersonii, is also called "lemon-scented teatree", and produces a similar lemony essential oil.
