The short answer is no, not for the fourth one, because Alvin and the Chipmunks: The Road Chip already filled that slot in 2015.
If you are asking if there will be a chipmunks 4, the confusion usually comes from people meaning a fourth new movie in a different counting system, or a possible Alvin and the Chipmunks 5 style follow-up.

The franchise already has four live-action theatrical films, so any new sequel would be a fifth movie, not a fourth.
That is why search results, fan pages, and rumor posts often talk past each other, and why you may see mixed references to The Road Chip, Alvin & The Chipmunks, and other titles in the same discussion.
The Direct Answer And Why The Query Is Confusing

Alvin and the Chipmunks: The Road Chip already served as the fourth live-action movie, so there is no separate fourth film waiting to happen.
If you are looking for a possible follow-up, you are really asking about Alvin and the Chipmunks 5, not a new fourth installment.
The Fourth Live-Action Movie Already Came Out In 2015
The Road Chip came out in 2015 and stands as the fourth and final live-action entry in the series.
People often shorten the title to “Chipmunks 4” or search for “Alvin and the Chipmunks movie” without realizing the numbering already happened.
Why Some Fans Actually Mean A Fifth Movie
Many fans use “fourth movie” to mean “the next one after the older trilogy.”
That leads to mixed wording like Alvin & The Chipmunks 4 or Alvin and the Chipmunks 5, especially in older posts and reposted lists.
How Rumor Pages And Fan Listings Create Confusion
Some recent blog posts, interactive maps of movie series, and fan listings keep recycling incomplete franchise counts.
This gets even messier when search results sit next to unrelated titles like Spongebob Squarepants or studio references to Walt Disney Pictures, which have nothing to do with the Chipmunks films.
Where The Fourth Film Fits In The Series

The Road Chip comes near the end of the live-action run, after the earlier trilogy and before any future reboot or sequel.
The film brings back the core characters, keeps the road-trip comedy tone, and closes the chapter that started with the 2007 theatrical debut.
From The 2007 Movie To The Road Trip Finale
The modern film series began with Alvin and the Chipmunks, followed by Alvin and the Chipmunks: The Squeakquel.
Then came Chipwrecked and finally Alvin and the Chipmunks: The Road Chip.
By the time you reach The Road Chip, the franchise has already established its live-action rhythm through multiple studio-backed releases from 20th Century Fox and Bagdasarian Productions.
Main Cast, Voices, And Key Characters
Jason Lee plays Dave Seville in the live-action side, with chipmunks Alvin, Simon, and Theodore voiced by Justin Long, Matthew Gray Gubler, and Jesse McCartney.
David Cross appears as Ian Hawke, plus supporting names tied to the series such as Tony Hale and Kimberly Williams-Paisley.
Ross Bagdasarian, Ross Bagdasarian Sr., Ross Bagdasarian Jr., and Janice Karman have shaped the larger legacy behind the characters, which helps explain why the brand stayed consistent across eras.
What Happens In The Road Chip
In The Road Chip, the chipmunks think Dave is going to propose in Miami and may be planning to replace them with a new family member.
Alvin, Simon, and Theodore set off on a chaotic trip across places like New Orleans, mixing family panic, road comedy, and musical misadventures.
What The Future Looks Like As Of 2026

As of 2026, no one has announced a fifth live-action film.
The brand remains active in other forms, so the franchise continues.
No Official Fifth Live-Action Film Has Been Announced
No studio has confirmed Alvin and the Chipmunks 5 or a new theatrical sequel.
Any claims about a brand-new sequel should be treated as speculation unless a formal announcement arrives.
Why The Franchise Slowed Down After The Road Chip
Live-action family franchises often slow down when box office momentum shifts, cast schedules change, and studios reassess theatrical risk.
The Chipmunks films also faced a changing market where animation and hybrid family releases compete with big action movies for attention.
How TV and Older Animated Titles Kept the Brand Active
ALVINNN!!! and the Chipmunks kept the characters on TV. The chipettes—Brittany, Jeanette, and Eleanor—remained part of the wider brand identity.
Older animated titles like The Chipmunk Adventure, Alvin and the Chipmunks Meet Frankenstein, Alvin and the Chipmunks Meet the Wolfman, and Little Alvin and the Mini-Munks kept the catalog familiar.
Songs like The Chipmunk Song, Juicy Wiggle (Munk Remix), Uptown Funk, and Turn Down for What helped the music side stay recognizable.
