Mellis is a small village in Suffolk, England.

It has the largest area of unfenced common land in England.

In summer rare plants such as green-winged orchid, sulphur clover and adder's tongue fern flourish.

The 14th-century parish church of St Mary, restored in 1859 and 1900, is a Grade II* listed building.

[2] In 1968, Roger Deakin (1943 – 2006), writer and environmentalist, bought Walnut Tree Farm on the edge of Mellis Common, which he rebuilt over many years and where he lived until his death.
