Can somebody tell me the name of this flower? Thanks
Graham Chiu and Bamboo are right that the location and leaves will help people recognize it. But for now, I think it looks like some kind of geranium. Possibly even Geranium caespitosum as seen in this picture from Wikipedia:
Yours looks a little more purple though, ... so I dunno. Send some pictures of the leaves & the whole plant though if you can, and the experts here will surely nail it.
Okay, so no photos of the leaves are available, in which case, check out Geranium macrorrhizum - might be 'Bevan's variety', 'Ingerwersens variety' or 'Czakor', depends how accurate the colour of the flowers is in your photo, but the flowers have these long stamens with orange anthers, and the flower buds have the very fine, long filaments showing at the top, unlike many Geranium varieties.

I have had lots of my own masses of this plant and this is my knee jerk reaction to your picture. We have far better IDers on this site so this is but a start.
