!! Live Action TV
* One episode of ''Series/{{Angel}}'' (the one with the children's show puppets) had a kid named "Ratio Hornblower".
* ''Series/MondayMornings'' had a nice ActorAllusion. Ioan Gruffudd played a doctor and his boss asked him several times if he was familiar with the concept of "captain of his ship".
* ''Franchise/StarTrek'' pays homage to Hornblower a few times:
** In one episode of ''Series/StarTrekTheNextGeneration,'' Data is put in temporary command of a ship called the ''Sutherland'' where he proceeds to act as a very straight-faced MilitaryMaverick on a blockade.
** Jake Sisko, son of TheCaptain in ''Series/StarTrekDeepSpaceNine'', is a writer. Whenever the camera peeks in on the manuscript he's editing, though, it's text from ''Commodore Hornblower''.

!! Literature
* In one ''Literature/HonorHarrington'' novel, the title character is reading a ''Hornblower'' book. And, in fact, the whole series had its genesis as a "Hornblower In Space" book; the matching initials are a deliberate ShoutOut and the first book is dedicated to C.S. Forester himself.
* One book in the Alan Lewrie series (depicting a much less heroic naval hero) has the main character notice of a tall, thin, and melancholy-looking lieutenant in a threadbare uniform at the Admiralty during the Peace of Amiens--a tacit reference to Hornblower, who was without either a ship or half-pay during that time.
* The third ''Literature/CiaphasCain'' book mentions a navy commander named "Horatio Bugler."

!! Comicbook
* In the world of ''Comicbook/LeagueOfExtraordinaryGentlemen'' , Horatio Hornblower is their equivalent to ''UsefulNotes/LordNelson'' .

!! Video Games
* In ''Age of Pirates II'', a character named Horatio Hornblower will aid the player if they ask him the right questions.

!! Web Original
* It's a running joke on this very wiki to call ''Honor Harrington'' novels ''Horatio Hornblower IN SPACE!''
* In a parody rap song "Creator/JaneAusten is My Homegirl (Series/DowntonAbbey Rap)" by Pretty Darn Funny, one part says, one part referenced the dashing sailor. [[http://youtu.be/-b_xiWmFWgYhttp://youtu.be/-b_xiWmFWgY Watch it here.]]
-->My friend loves Phillip but, I'll have to show her, no man stills my heart like Horatio Hornblower.

!! Western Animation
