“Can I take money out of my 401(k) early?”

Usually yes, mechanically — but it tends to be expensive, and it's worth understanding exactly how before deciding.

A withdrawal before age 59½ generally means income tax on the amount plus, in many cases, an additional 10% early-withdrawal penalty. There are real exceptions (certain hardships, some medical costs, leaving your employer at 55 or later, and others), and the rules have specifics that depend on your situation.

Some plans also offer *loans* — borrowing from your own balance and paying yourself back with interest — which is a different mechanism with different tradeoffs, including what happens to the loan if you leave the job.

If you're looking at this question because money is tight right now, that's exactly the kind of situation where talking it through with someone who can see your whole picture helps more than any single rule of thumb. There may be a better door than the retirement account — and sometimes the retirement account genuinely is the right door. The point is to choose it, not fall through it.
