The likes of Michelle Obama, Hillary Clinton, Angelina Jolie, Alexa Chung, Jessica Biel, Naomi Campbell and Beyoncé have joined in the campaign and now you can help too.
It has been nearly a month since more than 200 schoolgirls were kidnapped in the middle of the night from their school in Nigeria.
The world has been slow to react to this barbaric act (terrorist organisation Boko Haram have taken responsibility), but now key influencers, celebrities and the public are really starting to get involved.
A social media campaign under the hashtag #BringBackOurGirls started trending in Nigeria two weeks ago and has now been tweeted more than one million times.
The likes of Michelle Obama, Hillary Clinton, Mala Yousafzai, Angelina Jolie, Beyoncé, Naomi Campbell, Alexa Chung and Jessica Biel have all added their voices to the campaign.
As well as demonstrations in Nigeria itself, protests have been held in at the Nigerian embassy in London, in Los Angeles and New York.
