The Geordie Shore star will front the currently-untitled four-part series, in which she spends time with different extreme cultures.
Scheduled to air in the spring, each episode will see the Celebrity Big Brother winner live with some of the world's most unique communities.
Among the culture groups she will integrate herself within are Geishas and Inuits.
She will discover their different beliefs, practices and style of living, while also attempting to stick to their rules.
Crosby said of her new show: "I am bursting with excitement about my new show with TLC. I literally want to run around shouting about it from the rooftops!
"When they told me about going to my first destination Japan, I screamed 'OMG!!!!!!! I CANT BELIEVE I'M GOING TO CHINA!!!!' The crew just put their head in their hands!"
Susanna Dinnage, General Manager at Discovery Networks UK & Ireland, added: "Charlotte Crosby is one-to-watch; she's adventurous, and relatable, and will make a great addition to the TLC family."
Crosby recently told Digital Spy that her series of Celebrity Big Brother was "a load of w**k".
