The 21-year-old has made 21 appearances for Liverpool and had a temporary switch at RB Leipzig earlier this campaign where he lifted the DFL-Supercup on debut.
Carvalho, who has been capped four times at under-21 level for Portugal, lacked game-time in Germany and joins Hull after being recalled by the Premier League leaders.
Head coach Liam Rosenior told Hull's official website: "I couldn't be happier. Everyone is aware of Fabio's ability, his qualities as a young player.
"Fabio is excited to be coming here and I'm delighted to be working with him to the end of the season. Technically, he's outstanding. He can assist, score and run in behind. He's brave, quick, very balanced and takes the ball.
"Fabio's got the ability to make a real impact on our season and get us to where we want to be."
