From Penny's Wikipedia entry:

In contrast to all other characters, Penny and her father's surname have not been revealed. Co-creator Bill Prady stated that Penny's last name will be revealed eventually. Executive producer Steve Molaro, however, has since stated her surname will remain a secret.

Now that Penny and Leonard are married, her last name is Hofstadter. Leonard got down on one knee in episode 2 of this season (9) and asked her, "Penny Hofstadter, will you stay married to me?" to which she said yes. Typically such formal proposals include middle names (and a maiden name in some cases) but since she doesn't have any, it was short and simple.

  • I'm quite surprised how you people imply that marriage automatically implies that her name has changed. Is it somehow required for the bride to change her name in the US? :/

    I didn't assume anything. The lines of the script had him calling her that. Jan 30 '18 at 18:04

After some research, this is what I found to be the latest update regarding Penny's last name (before she married Leonard) or her maiden name:

Writer Steve Molaro said: ‘[Eventually] we got nervous and superstitious about giving her one.’

He added: ‘It will always be [her married name] Hofstadter.’

The same information is present over various other websites as well.

It's TELLER.

An eagle-eyed fan on Reddit noticed Penny's last name mentioned in one of the packages with her materials in Season 2 episode 18 The Work Song Nanocluster.

Link to the Reddit post.
Link to the ScreenRant article.

While the Wikia for TBBT does not show any last names for Penny, it does however mention Teller as the last name for Penny's dad, mom and brother.
