From the original series to recent revivals, each performer has shaped the show’s legacy with unique interpretations and unforgettable performances. This guide presents a precise, chronological list of all main Doctor Who actors in order, highlighting their tenure and iconic roles.

The Original Doctor and Early Companions

The first Doctor, portrayed by William Hartnell, debuted in 1963. Though his time was brief, Hartnell set the tone for the role. The first companion, Laura Jackson, played by Barbara Wright, followed shortly after, establishing early chemistry. From Series 2 onward, Patrick Troughton brought eccentric charm as the Second Doctor, followed by Jon Pertwee’s dignified Third Doctor. The Fourth Doctor, Tom Baker, with his legendary long scarf and whimsical charm, became a cultural icon, starring from 1974 to 1981. His companion Sarah Jane Smith, introduced in 1973, brought intelligence and courage to the series.

The Fifth to Seventh Doctors and Key Companions

The Fifth Doctor, Peter Davison, brought a softer, more human touch from 1984 to 1986, paired with Nyssa, played by Mark Simon, who added depth. The Sixth Doctor, Colin Baker, known for bold style and intense performances, played from 1987 to 1989, often alongside Jo Grant and later Peri Brown. The Seventh Doctor, Sylvester McCoy, redefined the role with a darker, more enigmatic presence from 2005 to 2010, with Rose Tyler—played by Billie Piper—becoming a fan favorite.

The Eighth Doctor and Modern Casting Evolution

The Eighth Doctor, Doctor Paul McGann, portrayed a reflective, scholarly version from 2013 to 2014, with Rose Tyler returning briefly. The Ninth Doctor, David Tennant, reenergized the franchise from 2008 to 2010, followed by Matt Smith’s youthful, energetic portrayal from 2014 to 2017. The Tenth Doctor, Peter Capaldi, brought intensity and gravitas between 2017 and 2019. Each Doctor’s actor brought distinctive energy, expanding the show’s appeal across generations.

Lead Companions Through the Decades

Companions have evolved alongside Doctors, each bringing fresh perspectives. The First Companion Laura was followed by Jon Pertwee’s loyal Sarah Jane, then Joan Redding’s pragmatic Peri, Rose Tyler’s fiery Rose, Billie Piper’s tech-savvy Rose, and Freema Agyeman’s strong-willed Clara Oswald in the Eleventh Doctor’s era. Each companion’s arc deepens the emotional and narrative richness of the series.
