Thrissops (from Greek: θρῐ́ξ thrix, 'hair' and Greek: ὄψις ópsis 'look')^[1] is an extinct genus of stem-teleost fish from the Jurassic period (Kimmeridgian to Tithonian).^[2] Its fossils are known from the Solnhofen Limestone,^[3] as well as the Kimmeridge Clay.

Thrissops was a fast predatory fish about 60 centimetres (24 in) long, that fed on other bony fish.^[4] It had a streamlined body with a deeply cleft tail and only very small pelvic fins. Thrissops was one of the smaller members of the order Ichthyodectiformes, which also included giants like Xiphactinus and Saurodon.^[5]
