Vasily I Dmitriyevich (Russian: Василий I Дмитриевич; 30 December 1371 – 27 February 1425) was Grand Prince of Vladimir and Moscow from 1389. He was the heir of Dmitry Donskoy, who reigned from 1359 to 1389.
He entered an alliance with the Grand Duchy of Lithuania in 1392 and married Sophia, the only daughter of Vytautas, though the alliance turned out to be fragile, and they waged war against each other in 1406–1408.
