Mariko Peters (born April 22, 1969, in Berkeley, California, United States) is a former Dutch politician and civil servant as well as lawyer.

She then took a job as a human rights-lawyer at the Organization for Security and Co-operation in Europe (OSCE) mission in Bosnia and Herzegovina.

In June 2010 Mariko Peters was elected for a second term in Parliament, having again been placed fourth on the list of the GreenLeft party by the congress.

Among her achievements was the writing of a new Freedom of Information law[1] Wet Openbaarheid van Bestuur [nl] (Wob for short) which she led with a group of experts, crowd-sourcing the preamble in a competition.

The proposal was accompanied by an innovative software program[2] allowing citizens to access government information freely according to their interests, comment on it and share it by social media.
