Now-discontinued 14" and 16" MacBook Pros using the M1 Max chip or the M2 Max chip can do this, too.

Check Technical Specifications for details.

Mac notebooks that use base M1/M2/M3 chips, or that use M1/M2/M3 Pro chips, do not support this. So you'd be looking only at the high-end MacBook Pros.

MacBooks are no longer made. MacBook Airs and MacBook Pro are current.

Note: IAW the specs on Apple's web site, the MacBook Pro M3 Max models are the only ones that can handle 3 external displays.

Batman-15 Said:

"macbook display support: BLUF: Which MacBook or MacBook Pro can support three externally connected displays? These displays would be separate from the laptop display itself.[...]"

Getting 3 External Displays:

The J5 USB-C Dual HDMI Docking Station allows for more than two extra monitors. How so? Well, plug in a display projector the Mac using the USB-C Digital AV Multiport Adapter and then plug the J5 hub with 2 HDMI displays (one 4K), and then you'll have 3 external screens. It all mirrors and extends.

Note that if you do not need portability, an alternative to a MacBook might be a M2 Pro Mac mini, a M2 Max Mac Studio, or a (now discontinued) M1 Max Mac Studio.

Check Technical Specifications - but I think that the M2 Pro version of the Mac mini can drive three displays, and that the M1/M2 Max versions of the Mac Studio can drive five.
