Only if the amplifier has a headphone socket — many small practice amps do, and many larger ones do not. Plugging headphones into a speaker output is not an alternative and can damage the amplifier.
Why it is not universal
Many valve amplifiers and larger combos have no headphone stage at all, because they were designed to be heard through their speaker.
What not to do
Never connect headphones to a speaker output. The impedance and the voltages are wrong, and on a valve amplifier running without a load can be destructive.
What to look for instead
A socket marked Phones or Headphones, and ideally a note that it is speaker emulated.
Check your own manual before you plug anything in. Voltage, polarity and current draw differ from model to model, and the manufacturer’s figures take precedence over anything written here. A supply of the wrong polarity can damage a pedal in seconds, phantom power is safe for most microphones but not for every one, and the required voltage is printed next to the socket or stated in the manual — not inferred from a connector that happens to fit.
The questions players ask
Do all headphone outputs sound the same?
No. Some are voiced to imitate a miked speaker cabinet and sound convincing; others pass the raw signal and sound thin. The manual states which.
Which amps in your catalog have one?
All four in our amp family — the two Blackstar Debuts, the Fender Frontman 10G and the Champion II 25 — because in a flat it is the deciding feature.
