Her comment comes as Olympic organisers released a playlist for the opening event and the band didn't' feature.
Mellanie Chisholm told The Mirror newspaper: ''I don't know exactly where this list has come from, and obviously sometimes things come out that aren't quite right.
''But I'd be really upset if the Spice Girls weren't included in the Olympics, whether it be the opening or closing ceremonies or any other playlists, because I think we absolutely represented Britain in the 90s.
She continued: ''We literally flew the flag - and Geri even wore it - around the globe.''
The singer also known as Sporty Spice added: ''We were proud to be British and to be successful internationally, and we were the last band probably to do that.
''So I think it would be a real shame if we weren't acknowledged in some way at the Olympics.''
