Dmitry Yakovlevich Laptev (Russian:. . Дмитрий Яковлевич Лаптев; * 1701 Bolotowo, Pskov province; † 20 Januarjul / January 31 1771greg same place ) was a Russian polar explorer and naval officer.

Laptev, who joined the Russian Navy in 1718, first sailed the Gulf of Finland, before 1730 for the first time took part in an expedition to Arctic waters.

1739-1742 he participated in the " Great Northern Expedition" by Vitus Bering in part as one of the leaders of the Northern group. In an easterly direction from the mouth of the Lena protrudable, Laptev reached in the summer of 1739 the river Indigirka before his ship was trapped by ice. After a winter let Laptev build smaller boats to maneuver better in the ice can, and came this way in 1740 to the Cape Bykowski ( Быковский мыс ) east of the Kolyma estuary. After he had to spend the winter in the ice again, Laptev finally decided by land to the mouth of the Anadyr travel further on the southern edge of Chukotka, where he finally found a land route from the Anadyr fortress to the eastern Kamchatka.

In the course of this expedition by sea and by land he charted the Siberian coastline from the Lena mouth to the Kolyma. He also explored the catchment and the estuary of the Anadyr.

1741-1742 he returned and charted the Anadyr and the Penzhina. After this second expedition Laptev returned to the Baltic Fleet, where he retired in 1762.

After the Laptev Laptev street is named, those strait that separates the Liakhov Islands from the Siberian mainland and linking the East Siberian Sea with the likewise after him ( and his cousin Chariton Laptev ) named Laptev Sea.
