Poser (and Poser Pro) is a figure posing and rendering 3D computer graphics program distributed by Bondware. Poser is optimized for the 3D modeling of human figures. It enables beginners to produce basic animations and digital images, along with the extensive availability of third-party digital 3D models.

Poser is a single-threaded 3D rendering software package for the posing, animating, and rendering of 3D poly-mesh human and animal figures. It is published by Bondware and supported by Renderosity, a graphic 3D art content store. Poser allows the user to load figures, props, lighting, and cameras for both still and animated renderings.

Using a subset of the Alias object (OBJ) file format and a text-based markup for content files, Poser comes with a library of pre-rigged human, animal, robotic, and cartoon figures. The package also includes poses, hairpieces, props, textures, hand gestures, and facial expressions. As Poser itself does not allow for original modeling of objects, a large community market of artists has emerged, in which Poser content is created and sold through various third party channels.

Poser is available in multiple languages including English, Japanese, German, and French. Poser is available for both Microsoft Windows and Mac OS X operating systems. While Poser's interface has evolved since the product's introduction in 1995, the current Poser Pro 13 preserves many of the application's original interface elements in order to not alienate the legacy users from the newer versions.

Renderosity offers a selection of ready-to-use content to add to Poser's included runtime library of base content, including body and hand poses, materials, props, facial expressions, hairpieces, lights, cameras, and a Reyes-based render engine called Firefly, which supports nodes for the creation of complex materials. Furthermore, it provides import of sound, image, and video files, motion capture data and 3D content for the creation of scenes or the addition of new library items. Poser exports content in many 3D formats. Poser is capable of material editing, facial photo matching, dynamic hair, dynamic cloth and new figure rigging. Online content is also available. Python enables third-party developers to create additional features ranging from custom libraries, rendering engine control panels, metadata editors and utility scripts.

Poser is used to create original images ranging from human figures, human renderings of medical and industrial design illustrations, editorial illustrations, informational graphics, graphic novel illustrations, comics, and more.

Poser contains many animation capabilities and is regularly employed by broadcast professionals including animation staff at Fox Bones, Colbert Report and Jimmy Kimmel Live!, as well as in industry applications, such as in the animated instructions for automated checkout machines at Albertsons, Save-On stores and Wal-Mart, films including Star Trek fan-film, Star Trek: Aurora,The Misty Green Sky, and The Exigency. Poser characters and animations were used for early computer games from 'buddies' game creators ("Desert Rifle" games and "Cake shop" from Qi and ELEFUN(TM) game developers).^{[citation needed]} The software was also used in the eighth, ninth, and tenth seasons of Red vs. Blue, as well as the first three seasons of RWBY.

Standard Poser characters have been extensively used by European and US-based documentary production teams to graphically render the human body or virtual actors in digital scenes.^{[citation needed]} Humanoids printed in several science and technology magazines around the US are often Poser-rendered and post-worked models.^{[citation needed]}
