Muggleswick is a village and civil parish in North West County Durham, England. It is situated a few miles to the west of Consett.

The village has a number of farms and domestic dwellings as well as the Church of England church, generally accepted as dedicated to All Saints, and village hall (previously the school). Amenities other than that consist of the phone box with its adjacent litter bin. Agriculture is primarily sheep farming with some cattle and hay.

There are the ruins of a priory, once a hunting lodge for the Prior of Durham, which is a listed building. These are located near to the church.

The church as seen today is the result of rebuilding in the 19th century and additions and repairs in the 20th. The site is on a rise and indicates a possible pagan origin.

Between the church and the lych-gate is a headstone surrounded by railings, which is to the Mayor family.
There are a number of children who died young and the father who died in 1819 and the mother, Ann Mayor or Nannie Mayor, who died in 1860 aged 85 years. She kept a tavern by the side of the early railway, built over Muggleswick moors to take ironstone and limestone to the new works at Consett. The track of the railway is now a footpath known as Nannie Mayor's Incline.
The brass rails surrounding the tomb were placed by Ann Mayor's grandson who was an ironmaster at Dumbarton and has his tombstone next to his grandmother's.

The lych-gate is at the south-west corner of the churchyard and was erected in 1933 or 1934 to the memory of Utrick Alexander Ritson, 1843-1932, and his wife Annie, 1842-1919, who had lived at Calf Hall, just a field away from the church. The construction is of seasoned battleship teakwood which had come from HMS Powerful. The initials of their sons and daughters, who erected the gate, are carved into the posts.

Most of the interior of the church is of 20th century and commemorates events and persons of the RITSON family. Utrick Alexander Ritson was a coal owner and a man of stature on Tyneside and he used Calf Hall, just south of the church, as his country residence. The east window, the organ, the alter rails, the choir stalls, the pulpit and lectern are all Ritson memorials and two grandsons, one the holder of the V.C. are remembered on a plaque found on the south wall.
