Art & story archives
The 'anthro' section of DeviantArt contains a variety of PG-rated furry artwork, some of a very high quality.
Another non-specific-but-still-quite-furry art archive, intended primarily for non-photographic 2D artwork. No adult material.
Not-specifically-but-still-mostly furry art, story and music community.
Furry art and story community. The second most-active site for furry-specific art hosting after Fur Affinity.
Photo and video archive of fursuits, dating from their first appearance in the 1990s to the present day.
Artwork-based community website in the style of deviantART; also hosts stories, music, personal journals and forums. The combination of mostly-unrestricted content, relatively good uptime, and oodles of popular artists have made FA the most popular furry website as of 2016.
Once furry fandom's most active art archive, the VCL is still one of the largest, with over 300,000 pieces plus several thousand stories. However, the site lacks features that have drawn users elsewhere, while maintaining a barrier to entry through its application policy. Adult work may be segregated into subdirectories, but this doesn't help when viewing new work; if this is a concern, use the sieve and bookmark the result.
