Half Blood Prince Theory

No: HPFGUIDX 107521

Forgive me if someone has posted this before- I've looked over the 
posts from the last few days and no one seems to be actively putting 
this idea forwards, so I thought I throw it out there.

My flatmate and I (he thought of it, but I agree) believe that the 
Half Blood Prince is most likely to be Hagrid- the half blood refers 
not to being half-human or half-muggle, but half-giant.

The evidence:
-JKR has said that Harry Potter and the Half Blood Prince was 
originally the title of Chamber of Secrets, and that Chamber of 
Secrets holds more clues to the events of book 6 than any other. It 
is in CoS that we find out about Hagrid's past at Hogwarts. The only 
other big revelation in that novel is the one about Tom 
Riddle/Voldemort, and we know that Voldemort is not the HBP.

-We don't know all that much about Hagrid's giant-half of the family, 
except that his mother was the giantess Gridwulfa. The fact that her 
name was known to the wizards could indicate that she was an 
important person in the Giant community.

-In OoP the Grawp storyline is a HUGE loose end- and JKR wouldn't do 
that unless it was going to become significant in the next books. As 
Hagrid's relationship with Grawp develops, Hagrid will learn more 
about his family history.  Giants, being fairly primal creatures, 
won't accept a new leader if he's weak, like Grawp, but Hagrid makes 
up for physical weakness (giant-wise) in his strength of character, 
which I believe will allow him to take up his legacy as the Prince of 
Giants, playing a pivotal role in bringing the Giants to the side of 
the good guys. This will also provide Harry with a diversion from 
constantly thinking about his ultimate battle with Voldemort.

And wouldn't Malfoy be pissed off if Hagrid turned out to be 
royalty? :D
