Andrey Rublev was born in Moscow to Andrey Rublev Sr., a former professional boxer turned restaurant manager, and Marina Marenko (née Tyurakova; Russian: Тюракова), a tennis coach at the Spartak Tennis Club. His mother worked with tennis players such as Anna Kournikova and received the Medal of the Order "For Merit to the Fatherland" in 2009. She is also the mother of Anna Arina Marenko, Rublev's older half-sister and former professional tennis player.

Rublev has Austrian ancestry on his paternal side, through his grandmother Larisa Genrikhovna Rubleva. He often credits his paternal grandparents for raising him as a child for five days a week until he was 15. Rublev denies the claims his mother used to be harsh towards him: "She was definitely not harsh. My parents always did everything for me. They love me very much". His maternal grandfather, Andrey Fyodorovich Tyurakov was a pro-coach in Greco-Roman wrestling, an amateur tennis player and doubles partner of Boris Sobkin, a coach of professional tennis player Mikhail Youzhny and sparring partner of Grand Slam doubles champion Olga Morozova in her prime years.

In 2013, Belarusian Sergey Tarasevich became his other coach. Then Tarasevich was replaced by Fernando Vicente from Spain.

Rublev debuted in Luxembourg at age 13, getting his first win in his second competition in Phoenix. In the following years, Rublev could climb the third rounds in singles, and in December 2012, he won one of the top junior competitions, the Orange Bowl.

Next, in spring of 2013, Rublev achieved the NWU Pukke/RVTA Junior ITF 1 cup in Potchefstroom, South Africa. He successfully competed in following tournaments, especially on clay surface, including the Trofeo Bonfiglio in Milan, and became quarterfinalist at the 2014 Australian Open junior singles. At the doubles competition, he paired with German Alexander Zverev, reaching the quarterfinals. The first notable win was at the 2014 French Open junior singles, crushing Jaume Munar. There he also reached the semifinals with partner Stefan Kozlov, before being knocked down by Frenchmen and future winners Benjamin Bonzi / Quentin Halys. He became world No. 1 ITF Junior player on 9 June 2014, after winning the 2014 Junior French Open.

Shortly before Wimbledon, Rublev captured the cup at the Nike Junior International in Roehampton, England. In the Wimbledon Championships, he reached the third round, before being beaten by 1842nd-ranked Dutch Tim van Rijthoven in three tight sets. In doubles, Rublev and Kozlov lost to Brazilians Orlando Luz and Marcelo Zormann in three sets, attaining his first junior Grand Slam final in doubles.
