Olga Vasilyevna Shishigina (Russian: Ольга Васильевна Шишигина; born 23 December 1968) is a retired Kazakhstani track and field athlete who mainly competed in the 100 metres hurdles.

With the help of diligent training, she quickly entered the international level, where she competed with opponents from different countries.

Olga Shishigina's sports career began with a victory at the 1994 Asian Games in Hiroshima, she also won silver medals at the 1995 Summer (Gothenburg) and Winter (Barcelona) World Championships; followed by gold at the 1999 World Indoor Championships (Maebashi, Japan) and an Olympic triumph in 2000 in Sydney.

Despite the fact that she was loaded with training and competitions, she received higher education at the Kazakh State Academy of Tourism and Sports in 2002.

In an interview, she noted that she felt pride in patriotism and the enthusiastic echoes of her compatriots from the podium during the competition, and this gave her more motivation to win.

At the age of 7, a coach noticed her passion for sports and began to turn her into a future champion.

When Olga was 10 she got into the Olympic reserve and at 19 when she entered the national team of the Union, she unexpectedly got married.

In the late 80s, the girl began to experience a recession in physical terms, which is why she temporarily left the performances and focused on gaining the optimal form.

In almost all interviews she does not get tired of claiming that her victories are the merit of her husband - Dmitry Gridnev, since because of the competition, she dumped all household life on his shoulders, and withstood fatherhood in her opinion with dignity (took care of her son and home in her absence);[5] She managed to achieve success in the 90s.

However, the wind of change blew from Astana and in 2016 she became a deputy of the Mazhilis of the Parliament of the Republic of Kazakhstan of the sixth convocation, a member of the People's Democratic Party "Nur Otan" according to the party-list election.
