Oleg is a Meerkat who appears in the Compare The Market adverts. He is the adoptive son of Aleksandr Orlov.
Oleg was first seen as an infant in an advert that aired on Christmas Day 2013 where he was found on Aleksandr's doorstep by his sidekick Sergei on stormy night. At first, Aleksandr was reluctant to take him in, but changed his mind when Oleg called him Dada.
A few days later, a toy Oleg was released. He also appeared in the brand's Coronation Street sponsorship idents.
In 2014, Oleg went to Africa with Aleksandr and Sergei. There was also a toy of Oleg in a safari outfit released. In December that year, as Aleksandr and Sergei were ready to leave, they find out that Oleg wanted to stay, and so they left him in Africa with the meerkats there.
In 2019, Oleg and his friend Ayana's home in Africa was subsequently destroyed by multiple diggers and bulldozers. The pair travelled to San Francisco where they met Aleksandr and Sergei, who were happy to see Oleg again. Following this, Oleg and Ayana appear with Aleksandr and Sergei in the follow up adverts.
In 2020, a toy sleepy version of Oleg was released.
