Alexandru Coconul (14 August 1611 – 26 June 1632) was Hospodar and Voivode of Wallachia from 1623 to 1627 and Hospodar of Moldavia from 1629 to 1630.
He was the son of Radu Mihnea, who also was a Hospodar.
He married Ruxandra Beglitzi.
He was the last of Vlad the Impaler's Romanian bloodline.

It is possible that Radu Gioan Bey was his illegitimate son, however no documents reveal a legitimate heir.
