Romana, short for Romanadvoratrelundar, is a fictional character in the long-running British science fiction television series Doctor Who. A Time Lady from the planet Gallifrey, she is a companion to the Fourth Doctor.
As a Time Lady, Romana is able to regenerate, having had two on-screen incarnations with somewhat different personalities (dubbed Romana I and Romana II by fans). Romana I was played by Mary Tamm from 1978 to 1979. When Tamm chose not to sign on for a second season, the part was recast. Romana II was played by Lalla Ward from 1979 to 1981 regularly and then again in 1983 and 1993 as a guest.
Romana is one of only two members of the Doctor's own race to travel with him in the original television series. The other is Susan Foreman, the Doctor's granddaughter, although Susan is never explicitly identified as a Time Lady.
