The female who can hit the highest note is Mariah Carey and Whitney Houston
Mariah Carey
Mariah Carey had lots of number one songs, but the "greatest hit by Mariah Carey was One Sweet Day by Mariah Carey & Boyz II Men. One Sweet Day was the all time greatest hit in pop music." So, One Sweet Day was not only Mariah's greatest hit, but it was the greatest hit ever.

They say Yma Sumac holds the record for posessing a four-octave vocal range. The widest range ever known to man. But Mariah Carey's range is actually more than that. Her range was reported to be 8 octaves. Which obviously isn't true. Now back to the answer. Mariah Carey's octave range is four octaves and two notes. She sings from a D3 all the way up to her highest note which is a F7#. That's the world record. So Yma Sumac doesn't hold the record.

Here are some of the highest points of her whistle: Listen to the beginning of "Dreamlover" Listen carefully at around 2:39-2:43 of "Inseperable" Listen to the beginning of "Fantasy"
The 1990's.
Luther Vandross.
Trey Lorenz
Highest notes: G#7 (Live performance of "Emotions" at the 1991 MTV VMA's, and again on Arsenio Hall), F7 (In the song "All In Your Mind") I'm not really good at math but in my opinion I would have to say Emotion is her highest note.
