sadiq

Sadiq is a masculine given name of Arabic origin meaning "truthful" or "trustworthy." It is used across Muslim-majority regions and among diaspora communities, and is found in many languages with various spellings, including Siddiq, Siddique, Seddique, and Sadik. The root word ṣādiq conveys honesty and reliability, and the name is often chosen to reflect these qualities. In Islam, Al-Sadiq is also one of the 99 names of Allah, reinforcing its positive association with truth.

The name is commonly used as a first name in the Arab world, South Asia (where it is widespread in Pakistan, India, and Bangladesh), and among East African and Southeast Asian communities. It is less commonly used as a surname, but some families bear it as a patronymic or as part of compound names such as Abdul-Sadiq.

Notable individuals with the given name include Sadiq Khan (born 1970), a British politician who has served as Mayor of London since 2016. The name also appears in literature and film and has produced bearers across different fields.

Variants and related surnames include Siddiq, Siddique, Siddiqui, Seddique, and Sadik; these forms share the same semantic root and are found in diverse cultural contexts.
