Tatiana Vladimirovna Grigorieva (Russian: Татьяна Владимировна Григорьева; born 8 October 1975) is a retired Australian pole vaulter.

On a night when Cathy Freeman won gold, the Australian home audience had a real bonus in seeing Grigorieva jump a personal best and win silver.

At the 2001 World Championships in Canada, competing against the odds due to an injury restricted campaign, Grigorieva equalled her personal best to claim fourth.

She had a successful season, making the finals of the World Championships and winning the Osaka Grand Prix to retain her Japanese record set in 2001.

In November 2007, Grigorieva and her partner Plamen Milanov opened the "Caffe e Gelato Milany" on Racecourse Road in the Brisbane suburb of Hamilton.
