Hot House is an album by Steve Lacy and Mal Waldron released on the RCA Novus label in 1991.

It features duo performances of tunes written by Herbie Nichols, Tadd Dameron, Bud Powell, Thelonious Monk.

Sidney Bechet, Duke Ellington along with two compositions by Waldron and one by Lacy.

The Allmusic review by Chris Kelsey awarded the album 4.5 stars, stating: "Though certain gestures recur during the course of their improvisations, those gestures (the raw materials of improvisation) are smaller than those used by younger, less resourceful players.

It's as if, instead of building a house made out of prefabricated materials, Lacy and Waldron cut down the trees, split the logs, plane the wood, and nail the boards together one by one.
