Mehmed I Çelebi (Ottoman: چلبی محمد, Mehmed I or Mehmed Çelebi) (1390, Bursa – May 26, 1421, Edirne, Ottoman Empire) was a Sultan of the Ottoman Empire (Rûm) from 1413 to 1421. He was one of the sons of Bayezid I and Devlet Hatun.
After the Ottoman Interregnum, when Mehmed stood as victor in 1413, he crowned himself sultan in Edirne. He restored the empire, moved the capital from Bursa to Edirne, and conquered parts of Albania, the Jandarid emirate, and the Armenian Kingdom of Cilicia from the Mamelukes. Taking many of his achievements into consideration, Mehmed is widely known as the "second founder" of the Ottoman Empire.

Reign of Mehmed I, as Sultan of the re-united empire, had lasted only eight years. But he had been an independent prince for nearly the whole preceding period of eleven years that passed between his father's captivity at Ankara and his own final victory over his brother Musa Çelebi at Chamurli.
He was buried in Bursa, in a mausoleum erected by himself near the celebrated mosque which he built there, and which, from its decorations of green porcelain, is called the Green Mosque. Mehmed I also completed the mosque at Bursa, which his grandfather Murad I had commenced, but which had been neglected during in reign of Bayezid. Mehmed founded in the vicinity of his own mosque and mausoleum two other characteristic institutions, one a school, and one a refectory for the poor both of which he endowed with royal munificence.
