Andrei Dimitrievich Chekov (also known as Aleksei Mikhailovich Chekov) was a Human who lived in the early 23rd century. He was married to a wife, Larisa, and had one child, Pavel Chekov, who was born in the year 2245. (ST video game: Starship Creator)
- While the canon version of Andrei Chekov has never appeared onscreen, his existence is proven by his son's full name: 'Pavel Andreivich Chekov' (which has been spoken onscreen in TOS episode: "The Way to Eden"). Under Russian patronymic naming rules, Pavel's father must therefore be named Andrei.
- Star Trek II Biographies calls him Aleksei Chekov, perhaps because the author was unaware that Andreievich was a patronymic.
During a nightmare induced by Illusionists in 2273, Pavel Chekov dreamed that his father was trapped in a burning house. (TOS comic: "Chekov's Choice")
