Twisters levelled Joplin, Missouri last month (May11) and claimed the lives of 120 locals and left many more without homes.
The star has teamed up with the online Joplin Tornado Relief eBay Charity Auction to help victims in the area trying to rebuild.
Auction organiser, Tyler Childs tells Fox News, "Jenna has been just amazing. She's originally from Missouri and she donated a set visit to The Office. We were hoping that maybe she could sign a DVD set of The Office, but she really pressed for the set visit - something they (stars) rarely do - and she made it happen.”
The exclusive set visit will include access to a live rehearsal and taping, a private tour, lunch, which Fischer says is more like a "huge buffet with tons of different food stations like you might see in Vegas," and personal photos with the cast members.
Other items up for bid at the auction include a meet and greet with rockers Coldplay and a pair of tickets to see country star Tim McGraw in concert.
