Atatürkist Thought Association

The Atatürkist Thought Association (Atatürkçü Düşünce Derneği; ADD) is a secularist organization that espouses Atatürkism, the ideas of Mustafa Kemal Atatürk, the founder of the Republic of Turkey. It was founded by Hıfzı Veldet Velidedeoğlu, Muammer Aksoy, Hüsnü A. Göksel and Bahriye Üçok.

The association is opposed to the Islamist tenets enacted by Ayatollah Ruhollah Khomeini in Iran and wants to ensure that religion and state remain separate in Turkey. The organization is known for initiating court cases against web sites which insult Atatürk, or with links to sites that insult Atatürk. It is credited with organising the 2007 Republic Protests.

People associated with ADD include mayor of Istanbul Ekrem İmamoğlu, former President of the Constitutional Court of Turkey Yekta Güngör Özden, former General Şener Eruygur (its head in 2009) and Tansel Çölaşan (its head since 2010).
