Tuda Mengu (also known as Tode Mongke and Tudamongke; Mongolian: Тодмөнх, romanized: Todmönkh or Tudamönkh, lit.

'Eternal Brightness'; Turki/Kypchak: تودا منکو; died 1287) was Khan of the Golden Horde, a division of the Mongol Empire, from 1280 until his death in 1287.

However, he did keep good contact with Mamluk Sultanate in Egypt against Ilkhanate who was faithless enemy of both states.

Rashid Ad-din wrote that he was willing to keep good relations with Kublai khan and released his son Nomoghan to Yuan Court.

During his government, the influence of Nogai Khan greatly increased in the Golden Horde, and there was a second attack against Hungary in 1284/1285, which was a total disaster for his army.
