Jamal at the Penthouse is an album by jazz pianist Ahmad Jamal, recorded live at the Penthouse jazz club in Seattle and released by Argo Records in 1959. This album, unlike other Ahmad Jamal albums, features his trio with a 15-piece string section led by conductor Joe Kennedy.

Jamal at the Penthouse breaks away Jamal from his usual trio setting to an orchestra setting, with his trio still present. Scott Yanow from Allmusic gave the album a three stars out of five rating, saying:

"This LP was a change of pace for pianist Ahmad Jamal, whose trio (with bassist Israel Crosby and drummer Vernel Fournier) is joined by a 15-piece string section arranged and conducted by Joe Kennedy. The interpretations are generally pretty, but with enough variety to hold one's interest."
