This list of fossil arthropods described in 2017 is a list of new taxa of trilobites, fossil insects, crustaceans, arachnids and other fossil arthropods of every kind that are scheduled to be described during the year 2017, as well as other significant discoveries and events related to arthropod paleontology that are scheduled to occur in the year 2017.

Arachnids

Research

• A study on the anatomy of the Carboniferous whip spider Graeophonus anglicus, as well as on the phylogenetic relationships of fossil whip spiders, is published by Garwood et al. (2017).
• A study on the morphological diversity of fossil species belonging to the family Archaeidae compared with the diversity of extant species is published by Wood (2017).
• A specimen of the tick species Cornupalpatum burmanicum entangled in a pennaceous feather of an early bird or non-avian pennaraptoran theropod is described from the Cretaceous amber from Myanmar by Peñalver et al. (2017).

Other arthropods

Research

• Nielsen, Rasmussen & Harper (2017) confirm the presence of dimorphism in a large sample of individuals of Isoxys volucris from the Cambrian Sirius Passet Lagerstätte (Greenland), which they interpret as likely sexual dimorphism.
• A redescription of Utahcaris orion based on a restudy of the original material is published by Legg & Pates (2017).
• A study on the phylogenetic relationships of Enalikter aphson is published by Parry, Legg & Sutton (2017), who support the original interpretation of the species as an arthropod.
• A study on the lateral tail flexibility in the eurypterid Slimonia acuminata based on a new specimen is published by Persons & Acorn (2017).
• Traces produced by swimming eurypterids are described from the Silurian Williamsville Formation (Ontario, Canada) and Tonoloway Formation (Pennsylvania, United States) by Vrazo & Ciurca (2017), who name a new ichnotaxon Arcuites bertiensis.
• Description of the anatomy of the Triassic horseshoe crab species Yunnanolimulus luopingensis based on specimens with well preserved appendages and soft tissues, recovered from the Guanling Formation (China), is published by Hu et al. (2017).
• A study on the phylogenetic relationships of Rhyniognatha hirsti is published by Haug & Haug (2017) who consider this taxon to be more likely a myriapod (possibly a centipede) rather than an insect.
• A study on the age of the Cowie Harbour Fish Bed (Scotland, United Kingdom), containing fish and arthropod fossils (including the millipede Pneumodesmus newmani), is published by Suarez et al. (2017).
• A study on the microstructural details of the cuticle of the concavicarid thylacocephalans from the Devonian (Famennian) of Poland, identifying possible remains of sensory system, is published by Broda & Zatoń (2017).
• A review of the research history, distribution, anatomy, ontogeny and inferred mode of life of Agnostus pisiformis is published by Eriksson & Horn (2017), who also present enlarged three-dimensional sculptural models of members of the species.
• A restudy of the Burgess Shale arthropod Habelia based on known and new specimens is published by Aria & Caron (2017), who interpret Habelia as a close relative of Sanctacaris uncata and name a new arachnomorph order Habeliida.
