Penny's last name has apparently been revealed as "Johnston", but I can't find any references on the matter. I left a comment on the Penny's page asking for someone to cite a reference, but no one has answered as of yet. Unless it's been revealed in accessible episode transcripts, and I just don't know about it. Suggestions?
Yes, I have have been watching TBBT since the beginning and I am positive they have NEVER mentioned it and it has really been bugging me. I have heard rumour that it is Johnston and Longbottom...I'm sorry if this wasn't very helpful I just wanted to state my opinion!!!!!!
In season 7 episode 9, it was revealed that Penny had unknowingly been married to Zack, whose last name was Johnson, meaning her last name was Johnson but no longer is.
Like the previous commenter said, she would have had to fill out name change documents to change her surname to her ex's surname. Getting married does not automatically change your surname in the US. So her last name was never Johnson, she didn't even know she was really married to Zac. Her last name has not been revealed.
Steps that must be taken to change your name after marriage:
Get your marriage license. Before you can change your name, you'll need the original (or certified) marriage license with the raised seal and your new last name on it. ...
Change your Social Security card. ...
Change your license at the DMV. ...
Change your bank accounts. ...
Penny has a last name, we just won't ever find out what it is. Penny (played by Kaley Cuoco) last name has remained a mystery and Kaley along with the show's writers and producers are now vigilant that it is not revealed. Executive producer Steve Molaro told Vulture, "We're kind of a superstitious lot here. We've made it this far without knowing Penny's last name. I think we're good not finding out."

OMG no no no no no....Wyatt is her father's first name, not "Bob."
Does anyone here actually WATCH THE SHOW?? First, it's "Penny's father's name was Rostenkowski" which is inaccurate; that's Bernadette's maiden name. Now it's "her dad's name is Bob Wyatt" which is crap. JEEZ
Its Joy and is revealed on the Serial Apeist poster in the background of Season 10 episode 6. Leonard gets upset about a fan wanting to take a picture with her on his phone. If you freeze frame you will see her credit for the original movie... Starting Penny Joye.
Thought I had it. I went back and checked it on my laptop with better resolution. My TV kept making Johnny look like Penny and it seemed like the only place she could have exposed the maiden name. Guess only Lorre and Prady REALLY know.
So Chuck Lorre has done a interview where he did confirm her actual last name is Barrington. However... It's never once been shown or spoken in a episode and may never. But Chuck's given maiden name for Penny's family is Barrington. Tho... I'm not sure if this counts because as the writer Barrington is only a idea until it actually makes it on the show. The fact that the main actress of her only two movies didn't have her name credited at her big-ish comic Con signing leads me to believe it will remain a mystery.

just because she dots the "i" with hearts dose not mean that the name must contain i. i mean it is possible, but i know sevrel people who dotted all the "i" with hearts, but still had no "i" in their last name(s), it might just be one of those wired thing you do for no reasone. but i do see your point
