Pieter van der Does (Leiden, 1562 - São Tomé Island, 24 October 1599) was a Dutch naval commander.
In 1587, he was also bailiff and dijkgraaf of the Rijnland water board, and in 1588 chief schout of Leiden.
For his services the States of Holland and West Friesland granted him the fiefdoms of Vriesekoop and Rijnsaterwoude and the title of jonkheer.
In May 1599, he led a Dutch and Zeeland fleet which set out to blockade the Iberian coast as part of the Eighty Years' War.
It then moved to attack Spanish possessions in West Africa around Sao Tomé, where Van Der Does died, either of wounds received at Las Palmas or of Malaria.
