The churchyard at Llangedwyn is now an irregular 'butterfly' shape, due to extensions on both the south in 1870 and the east (in 1905 and later).
Originally, it may have had an elliptical form but the outline has been modified through time, and the best traces of its curvilinear nature are fossilised on the south-eastern side.
It occupies flat ground on the edge of the northern terrace of the River Tanat, though well back from the river, at a place where a small stream runs off the hill to the north.
It is well maintained and interments continue in the north-western sector of the original churchyard.
 A low, spread bank, 0.3m high, surmounted by three yews, represents the former boundary on the east.
To the south of the church is a natural scarp nearly 2m high which almost certainly functioned as the earliest boundary on this side.
Gravestones are well spaced on the north and west, and more closely packed on the south and in the extensions.
Slate memorials of the 19th century predominate, but there is a table tomb of 1734 to the east of the chancel.

The most interesting feature is the ring headed cross slab set against the east wall of the chancel.
It is said to have been discovered in the walling of the old church taken down in 1869.
This should be 10th century or earlier in date.

The churchyard contains two CWGC registered war graves, a soldier of the Devonshire Regiment of World War I and an officer of the 1st Royal Dragoons of World War II (Lieutenant Watkin Williams-Wynn, son of Sir Watkin Williams-Wynn, 8th Baronet).
