The main commemoration in Prescot is the Civic War Memorial. Built in 1916 on the junction of West Street and Church Street. More recently it was been moved to the south side of St Mary's Church. Engraved on it are the names of 147 men living in Prescot at the time of the outbreak of war and who died. Within St Mary's is a further commemoration consisting of 4 oak panels attached. These panels hold the names of 150 men, nominated by family or friends.

St Mary's Church has other commemorations including a large window dedicated to the memory Arthur Frederick Evans of the Royal Air Force who was killed in a bombing raid.

There are also a number of commemorations in other churches, including the Methodist and United Reform Churches.
