Hamlet

Hamlet was a play written by William Shakespeare. It was also the name of the titular prince of Denmark featured in the same play.

Hamlet and the Doctor
The idea for Hamlet was first discussed at the court of Elizabeth I. The First Doctor, Ian, Barbara and Vicki used the Time-Space Visualiser to witness Shakespeare's initial rejection of Francis Bacon's thoughts on writing a play about Hamlet. They then saw Shakespeare appear to warm to the idea, once he'd left Bacon's presence. (DW: The Chase)

The First Doctor collaborated with Shakespeare between drafts one and two (PDA: Byzantium!) and the Fourth Doctor helped Shakespeare write down the final draft of Hamlet after he sprained his wrist writing sonnets. This manuscript was acquired by Scaroth in the 20th century (DW: City of Death)

Upon finding a number of Nimon, the Fourth Doctor quoted Hamlet in saying "oh my prophetic soul." (DW: The Horns of Nimon)

The Tenth Doctor and Martha Jones visited Shakespeare in 1599. They inspired Shakespeare to write about father-son relationships, which is the main theme of Hamlet. Shakespeare also confused the name of his deceased son, Hamnet, with Hamlet. (DW: The Shakespeare Code)
 * This is a nod to the theory that Hamlet's name actually was inspired by Hamnet. 

Hamlet and other races
The Daleks quoted various lines from Hamlet while working on a time machine with Professor Osric. (BFA: The Time of the Daleks)

Behind the scenes
In The Chase, Bacon speaks of Hamlet as if he's common knowledge. Indeed, Shakespeare warms to the idea without ever having been told who Hamlet was. The direct implication is that Hamlet is a real person in the DWU. This marks a clear distinction between the DWU and our world. In the real world, Shakespeare never intended that Hamlet be taken as a biography. The character of Hamlet is an entire fiction.
