Umbrella

The Doctor's umbrella was one of several umbrellas owned by the Doctor.

Second Doctor
The Second Doctor carried an umbrella on the Gond planet because of the "twin suns. It's probably hot." Then he used it as defense against vaporisation. (TV: The Krotons)

Fourth Doctor
While visiting Derbyshire in 1979, the Fourth Doctor warned Leela that she would need an umbrella. (AUDIO: Trail of the White Worm)

The Fourth Doctor occasionally kept a multicoloured umbrella in his console room's hatstand. (TV: The Stones of Blood, Destiny of the Daleks)

Sixth Doctor
The Sixth Doctor was known to occasionally carry a bright, multicoloured umbrella. He brought it with him on a relaxing lakeside fishing trip. (TV: The Two Doctors) He also used it at least once as protection, while about to be stoned. (TV: The Trial of a Time Lord:The Mysterious Planet) He last had it with him when he crashed-landed and regenerated. (TV: Time and the Rani) It was later left behind on Lakertya by the Seventh Doctor during his wardrobe change.

Seventh Doctor
The Seventh Doctor usually carried an umbrella as part of his day-to-day outfit, whether the occasion called for it or not. He initially carried a black umbrella with a whangee handle. (TV: Time and the Rani, Paradise Towers) Eventually he acquired a new umbrella, with an elaborate handle in the shape of a large red question mark. (TV: Delta and the Bannermen)

On the planet Svartos, the Doctor saved himself from slipping off a sheer ice cliff by hanging from his umbrella. (TV: Dragonfire)

The Doctor was known to measure objects with his umbrella. (TV: Remembrance of the Daleks)

The question-mark umbrella handle was known to split in half and unfold into a seat, allowing the Doctor to plant the umbrella into the ground and use it as a makeshift stool. (DWM: Planet of the Dead, PROSE: Storm Harvest )

A secret compartment in the Doctor's umbrella concealed a vial of Gallifreyan restorative. (COMIC: The Forgotten)

When not in use, the Seventh Doctor's umbrella could often be seen resting on the hatstand in the TARDIS console room.

The Eighth Doctor gave Bernice Summerfield this umbrella, when they met each other, after he regenerated. (PROSE: The Dying Days)

Eleventh Doctor
The Doctor compared the patchwork people Auntie and Uncle to his old umbrella. (TV: The Doctor's Wife)

Behind the scenes
The non-canon Ninth Doctor kept a plain black umbrella in an umbrella stand, which the Master had a habit of leaving in the TARDIS' zeppelin hangar. (WC: ''Scream of the Shalka)
