Felpham (/ˈfɛlpəm/, FEL-pəm, locally /-fəm/ or /-θəm/, thəm) is a village and civil parish in the Arun District of West Sussex, England. Although sometimes considered part of the urban area of greater Bognor Regis, it is a village and civil parish in its own right, having an area of 1.645 square miles, (4.26 km),² with a population of 9,611 people that is still growing (2001 census). The population at the 2011 Census was 9,746.

Felpham lies on the B2259 coastal road.

The 12th century Anglican parish church is dedicated to the Virgin Mary. There is also a Methodist church close to the three-way junction of Felpham Way, Flansham Lane and Middleton Road, in the east of the village.

Felpham is mentioned in a charter of 953 by which King Eadred granted thirty hides of land there to his mother Queen Eadgifu. It was mentioned in the Domesday Book of the 11th century, under the hundred of Binstead: "St Edward's Abbey [Shaftesbury] holds and held Felpham before 1066..." Its value before 1066 was said to be £10.

The poet William Blake was introduced to the village by his friend William Hayley and lived in Felpham for three years between 1800 and 1803. He wrote Milton: A Poem in Two Books, while living in a house now named Blake’s Cottage. The poem contains the line about "England's green and pleasant land", today known as the anthem "Jerusalem", which were inspired by Blake's "evident pleasure" in the Felpham countryside. The cottage where he lived is depicted in the illustrations for the poem. It lies within the original village, close to the Fox public house. Of the village he wrote:

Away to sweet Felpham for heaven is there:
The Ladder of Angels descends through the air
On the turrett its spiral does softly descend
Through the village it winds, at my cot it does end.

The "turrett" in the verse is Hayley's house, east of the church, which he built around 1800. It was in Felpham that Blake had his altercation with the drunken soldier John Scofield, who was trespassing in his garden. This led to Blake's trial for sedition because of Scofield's allegation that he had cursed the king. Blake has a road named after him, Blake's Road, the road on which his former residence is sited, and a memorial window dedicated to him in St Mary's Church.

Blake's host, Hayley, was also famous in his day for having turned down the offer of the position of poet laureate in 1790.^{[citation needed]}
