Shams al-din Muhammad Juvayni (Persian: شمس‌الدین محمد جوینی) was a Persian statesman and member of the Juvayni family. He served as the state treasurer (mustawfi) of the Khwarazmshah Ala al-Din Muhammad II (r. 1200–1220) and his son Jalal ad-Din Mingburnu (r. 1220–1231).

Shams al-Din Muhammad had a son named Baha al-Din Muhammad Juvayni, whose sons Ata-Malik Juvayni and Shams al-Din Juvayni would become influential figures in the early days of Ilkhanate rule in Iran.
