Marciology is the ninth studio album by American rapper and producer Roc Marciano, released on March 29, 2024, through Pimpire Records and Marci Enterprises.

Marciology received positive reviews from critics, noting its eerie, neo-noir inspired soundscapes and sharp, witty rhymes.

[6] Editors at Pitchfork scored this release 8.1 out of 10 and critic Dash Lewis declared Marciano "the godfather of underground rap" for his ability to mix 1990s influences with modern sounds to create his own style, making this "the decoder ring for an entire generation of hip-hop".

[7] Editors at Rolling Stone gave this release a "Hear This" label and critic Andre Gee wrote that "Marciology again demonstrates why Roc is one of rap's most unique voices" with "his slick diction and knack for stacking multi-syllabic rhymes together" and highlights specific tracks and vocal deliveries that show "an expert example of mastering the rules to break them".

He's singing on "Gold Crossbow" for a start, an irresistible set of drums that slap you round the face, with a lovely piece of piano that gives it an underlying sense of horror".
