Greyfriars Bobby (May 4, 1855 – January 14, 1872) was a Skye Terrier who became known in 19th-century Edinburgh for spending 14 years guarding the grave of his owner until he died himself on 14 January 1872. The story continues to be well known in Scotland, through several books and films. A prominent commemorative statue and nearby graves are a tourist attraction.

The best-known version of the story is that Bobby belonged to John Gray, who worked for the Edinburgh City Police as a nightwatchman. When John Gray died he was buried in Greyfriars Kirkyard, the kirkyard surrounding Greyfriars Kirk in the Old Town of Edinburgh. Bobby then became known locally, spending the rest of his life sitting on his master's grave.
