Oleg Igorevich Kuvaev (Russian: Олег Игоревич Куваев; born 6 February 1967) is a Russian-Israeli artist, designer and animator, known for his Masyanya flash-animated series.

Later, he would work in a variety of professions and places, including as a painter and sculptor for more than 10 years, until the time of the "Big Worldwide Web" come.

In his free time he experimented with various computer technologies including freshly appearing vector animation (macromedia flash).

Initially, the project started with ten short rough-made cartoons about a hooligan girl from Saint Petersburg, which would eventually become quite popular among the Russian-speaking community.

Full of fresh, indigenous humor (sometimes caustic and absurd but still kind at its core) the series about Masyanya appealed to the young generation whose life, interests, and problems they focused on, while simultaneously embodying an alternative to commercial mass-culture.

For example, Oleg Kuvaev had to apply to court to compel the closing of the shoddy commercial talk show At Masyanya’s broadcast at the Russian pop-music TV channel Muz-TV that was using this character illegally, without his permission.

Despite this, suddenly, in the middle of 2006 Oleg Kuvaev closed all projects he was working on and left the studio and the country, with almost no response whatsoever to the other workers of Mult.ru.
