East Beach, Shoeburyness is a picturesque and extensive sandy beach located on the eastern edge of the city of Southend-on-Sea in the United Kingdom. Situated right at the mouth of the Thames, this location attracts travelers with its calm atmosphere and a wide strip of grassy shore, which is perfect for family picnics away from the hustle and bustle of the central promenades.

The area is managed by the local council but is actually owned by the Ministry of Defence (MOD), which leases it out. This ownership structure has helped keep the beach clean and protect it from overdevelopment. In 2024, East Beach was awarded the prestigious Blue Flag for its high water quality and compliance with strict environmental standards.
One of the unique features of this place is its industrial past: at the beginning of the 20th century, a brick factory operated here, and observant tourists can still find fragments of old bricks in the sand. The landscape is complemented by the Shoeburyness Boom—an impressive row of concrete piles installed in the middle of the last century to protect the estuary and which is now a historical monument.
