Sir Roderick Glossop is a recurring fictional character in the comic novels and short stories of P. G. Wodehouse.

He went to school with Lord Emsworth, who states that Glossop was an unpleasant boy who had a nasty and superior manner.

[2] Glossop has a pleasant baritone voice, and as a penniless medical student, sang at smoking concerts.

[6] He is a well-known psychiatrist, and, according to Bertie, "practically every posh family in the country has called him in at one time or another".

"[8] When Bertie sees Glossop in "Sir Roderick Comes to Lunch", he describes Glossop as an "extraordinarily formidable old bird," stating: He had a pair of shaggy eyebrows which gave his eyes a piercing look which was not at all the sort of thing a fellow wanted to encounter on an empty stomach.

[12] Glossop obtains the use of Chuffnell Hall as a clinic, funded by J. Washburn Stoker.

Though they are not friendly towards each other in the early stories, Glossop bonds with Bertie in Thank You, Jeeves (1934) when they both have to endure going about the countryside wearing blackface.

[15] However, they become friends in Jeeves in the Offing, after they bond over their realization that they each stole biscuits from the school headmaster's study as children.

[18] Bertie continues to regard Sir Roderick Glossop as a friend in Much Obliged, Jeeves (1971).
