The Foreigners' Advisory Council is the oldest democratically elected representative body of foreigners at municipal level in the Federal Republic of Germany. It is the point of contact for municipal bodies for all matters concerning foreign residents. Its rights and duties are regulated in the Hessian municipal code.

In 1970, the municipal council decided to set up an advisory council for foreigners with the aim of promoting the social and societal integration of foreign employees. The Foreigners' Advisory Council was to be made up of representatives of the largest nationality groups, represent the interests of foreigners resident in Wiesbaden vis-à-vis the municipal authorities and provide advice on solving specific problems.

In September 1971, the "Regulations for the Foreigners' Advisory Council" were passed by the city council. It served as a model for foreigners' advisory councils that were later established nationwide. In November 1971, the guest workers from Greece, Italy, Yugoslavia, Portugal and Turkey living here elected the Wiesbaden Foreigners' Advisory Council for the first time, which was constituted on March 1, 1972.

From 1972-78, the legislative period of the Foreigners' Advisory Council lasted two years, after which the term of office was gradually extended from three to four years. From 2005, it was increased to five years.

The first Foreigners' Advisory Council had 17 full members and the same number of deputies. The number of members was set at 31 when the Foreigners' Advisory Council was enshrined in the Hessian Municipal Code in 1989. In the 2005-10 term of office, nine nations were represented. It has the right to speak in the city council and is also represented in the specialist committees of the city parliament.
