My most favorite are my own! Indian Watch and Missin Kissin, they aren't famous by any means, neither placed at all, they both ran around seven races before they were retired. As far as famous, the ones already named plus Alleged, which is my girls dad with War Adrimal and Man O War also in their bloodlines.
Red Rum because he was an exceptional horse, my mum actually met him. Best Mate again because he was an exceptional horse, had a nice story behind him and sadly died on the race track due to a heart attack I think it was.
Afleet Alex! I love him. He will always be my favorite racehorse. His Preakness stakes win was amazing. Falling to his knees in the far turn and still drawing off to win by a couple lengths. His picture is my avatar.
Scrappy T tripping Afleet Alex and then Alex falling to his knees in the Preakness stakes.

I LOVE 'The Cat' (Apache Cat) - those socks and that blaze, so flashy! All my Aussie favourites have been mentioned so far. Just want to add Carbine who sired some of the best racehorses in the late 1890's and early 1900's.
I would also like to add Brew, Australia's most famous one hit wonder. He won the 2000 Melbourne Cup at what SHOULD have been very long odds however punters were dismayed when the winnings were announced after the race as it seemed that every boozehound in the country had backed him last minute, drawn in by the name "Brew". Classic.
