Philip Walsingham Sergeant (27 January 1872, Notting Hill, London[1] – 20 October 1952)[2] was a British professional writer on chess and popular historical subjects.

[3][4] Harry Golombek writes that, "Without any pretensions to mastership, he represented Oxford University in the years 1892-5".

[3] Golombek considers A Century of British Chess probably Sergeant's best chess book, but opines that although Sergeant's chess books are lucidly written, they suffer from the defect that, as a non-master, he was not competent to deal with the annotational aspect of his work.

[5] The ISBN, where given, refers to that assigned to a later republication of the book by Dover Publications.

Sergeant wrote or co-wrote the following books on subjects other than chess.
