Penelope Dora Harvey Boothby (2 August 1881 – 22 February 1970) was an English tennis and badminton player.

[1] In Badminton, she won the 1909 All England Championships in Mixed doubles category.

In 1908, she won a silver medal in the women's singles event at the 1908 Summer Olympics.

[3] Also in 1909, she won the singles title of the British Covered Court Championships, played on wood courts at the Queen's Club in London, after defeating Madeline O’Neill in the final in straight sets.

1This was actually the all-comers final as Charlotte Cooper Sterry did not defend her 1908 Wimbledon title, which resulted in the winner of the all-comers final winning the challenge round and thus Wimbledon in 1909 by walkover.
