The Banu Tamim tribe (Arabic: بنو تميم), also known as the Bani Tamim tribe, are one of the main tribes of Arabia. Tamim, the ancestor of the tribe, is a direct descendant of Adnan and is thus considered an Ishmaelite tribe descending from Ishmael son of Abraham.
Today, descendants from the tribe live in the Arabian Peninsula and neighboring countries such as, Saudi Arabia, Kuwait, Iraq, Jordan, Syria, Tunisia, Egypt, Qatar, Oman, Bahrain, United Arab Emirates, Lebanon & the Palestine. The word Tamim in Arabic means strong and solid.
Among the tribe's members are:
- Jarīr - classical Arab poet
- Ahnaf ibn Qais - a Muslim general who lived during the time of the Prophet Muhammad 
- Khabbab ibn al-Aratt - Sahabi; companion of prophet Muhammad
- Al-Qa'qa'a ibn Amr at-Tamim i - Banu Tamim General who gathered an army from his tribe and helped conquer Persia.
- Muhammad ibn Abd al-Wahhab - Islamic scholar
- Muhammad Ibn al 'Uthaymīn (d. 2001 C.E.) - Saudi Arabian Islamic scholar
- House of Thani
- Abdur-Rahman ibn Nasir as-Sa'di

The Banu Tamim are an extremely large tribe. They were mostly localized in Najd (Saudi Arabia) in Pre-Islamic times, but have then expanded to all corners of the Arabian Peninsula in pursuit of the Islamic Conquests. Nowadays, they can be found as far east as Pakistan, known as Thaheem in the local language, and as far west as Morocco. The Banu Tamim often hold genealogy in high regard, carefully recording birth and family data (especially in the Arabian Peninsula).

- The Al Thani, ruling family of Qatar
- The Al ash-Sheikh family of the Grand Muftis of the Emirate of Diriyah, then the Emirate of Najd and now modern day Saudi Arabia
- From Musnad Ahmad ibn Hanbal ; "do not say of Bani Tamim anything but good, for indeed they are the severest of people in attacking the Dajjaal (Anti Christ)."
- In a Hadith collected in both Sahih al Bukhari and Sahih Musim Abu Hurairah said "I have loved the people of the tribe of Banu Tamim, ever since I heard three things the Messenger of Allah -peace be upon him- said about them. I heard him saying: "these people (of the tribe of Banu Tamim) would stand firm against the Dajjaal (Anti Christ)." When the Saddaqat (Donations for Charity in Islam) from that tribe came, the Messenger of Allah -peace be upon him- said: "these are the Saddaqat (charitable gifts) of our folk." A'ishah had a slave girl from that tribe, and the Prophet said to A'ishah, "Manumit her as she is a descendant of Ismaa'eel, peace be upon him."
