McDonald's

Writers often drop the apostrophe in McDonald's, producing McDonalds, Mc Donals, or Mc-Donalds. That small change is a misspelling and looks careless in formal writing.

Below: clear rules, copy-ready corrections for work, school, and casual writing, a quick memory trick, and related brand pitfalls so you can fix sentences immediately.

Quick answer: Which form is correct?

McDonald's - capital M, lowercase c, an apostrophe, and an s. Avoid McDonalds, Mc Donals, Mc-Donalds, or McDonals.

Use McDonald's for the restaurant or brand name exactly as shown.
In professional and academic contexts, preserve the brand's punctuation and capitalization.

Core explanation: what the apostrophe signals

The apostrophe in McDonald's reflects a possessive form (originally "of McDonald") and is part of the brand's official styling. Dropping it turns the name into a misspelling.

Treat brand punctuation as fixed: preserve it exactly.
If you say the possessive aloud ("McDonald's fries"), write the apostrophe.

Wrong: I grabbed lunch at McDonalds.
Right: I grabbed lunch at McDonald's.
Wrong: Mc-Donalds just opened downtown.
Right: McDonald's just opened downtown.
Wrong: The new McDonals sign is missing a letter.
Right: The new McDonald's sign is missing a letter.

Real usage: work, school, and casual examples

Keep the official form in emails, reports, essays, captions, and any public copy. Casual texts often omit the apostrophe, but written mistakes still stand out.

Work - Wrong: Please add McDonalds to the vendor list for the office lunch.
Work - Right: Please add McDonald's to the vendor list for the office lunch.
Work - Wrong: Can you include McDonalds in the sponsorship deck?
Work - Right: Can you include McDonald's in the sponsorship deck?
School - Wrong: I'm quoting McDonalds in my marketing essay.
School - Right: I'm quoting McDonald's in my marketing essay.
School - Wrong: Figure 2 compares sales at McDonalds and Burger King.
School - Right: Figure 2 compares sales at McDonald's and Burger King.
Casual - Wrong: Anyone up for McDonalds later?
Casual - Right: Anyone up for McDonald's later?
Casual - Wrong: Met them at Mc Donalds for coffee.
Casual - Right: Met them at McDonald's for coffee.

Examples to copy: ready-to-use sentences

Paste these into emails, papers, or messages; each preserves the brand's official styling.

Work: Order trays from McDonald's for the meeting.
Work: The McDonald's team will present the partnership terms tomorrow.
School: This case study on McDonald's highlights brand strategy.
School: Appendix A lists McDonald's menu changes over the decade.
Casual: Let's grab fries from McDonald's.
Casual: I'm getting McDonald's on my break.

Tools and habits that reduce brand-name errors

Keep a short saved list of brands you use often with their exact styling. Combine that with a quick pre-send checklist to catch slipped apostrophes without slowing your workflow.

Maintain a "brand style" note: McDonald's, Chick-fil-A, KFC, etc.
Run a grammar checker or a quick find to flag missing apostrophes before you send or submit.

How to fix your sentence: quick rewrites you can paste

Replace only the brand token when the rest of the sentence is fine. When possessives get awkward, rephrase instead of adding another apostrophe.

Checklist: Capital M + lowercase c, apostrophe + s, no internal space, no hyphen.
If you would write McDonald's's, rephrase to "the policy at McDonald's" or "McDonald's policy."

Wrong: Went to McDonalds.
Rewrite: I went to McDonald's.
Wrong: McDonalds serves cheaper meals on weekdays.
Rewrite: McDonald's serves cheaper meals on weekdays.
Wrong: The McDonalds's new app has a loyalty program.
Rewrite: The new McDonald's app has a loyalty program.

Try your own sentence

Test the whole sentence rather than the phrase alone - context often clarifies whether the possessive belongs.

Memory trick and quick practice

Mnemonic: Read it as "McDonald + 's" (McDonald's = the place of McDonald). If you can rephrase as "the X of McDonald," the apostrophe belongs.

Practice tip: Say the sentence aloud. If you naturally say "McDonald's," write the apostrophe.

If speech includes the possessive sound, include the apostrophe in writing.
Quick drill: Type McDonald's five times from memory, then type common mistakes (McDonalds, Mc-Donalds) to notice the difference.

Hyphenation and spacing: mistakes to avoid

Do not insert spaces or hyphens inside McDonald's. Wrong forms include: Mc Donalds, Mc-Donalds, and McDonalds. These are misspellings.

Also watch typographic substitutions: some editors swap straight apostrophes for curly quotes or other glyphs that can look off in headings or logos.

Wrong: Mc Donalds is on 5th Street.
Right: McDonald's is on 5th Street.
Wrong: Mc-Donalds reopened last week.
Right: McDonald's reopened last week.

Grammar notes: possessives, plurals, and punctuation with brands

Avoid doubling apostrophes like "McDonald's's." Rephrase to "the policy at McDonald's" or "McDonald's policy."

For multiple outlets, write "McDonald's restaurants" or "McDonald's locations." Don't pluralize McDonald's itself without context.

Prefer "the policy at McDonald's" over "McDonald's's policy."
To indicate several outlets, write "McDonald's locations" or "McDonald's restaurants."

Wrong: McDonalds' new campaign will launch next month.
Right: McDonald's new campaign will launch next month.
Wrong: All McDonalds are following the rule.
Right: All McDonald's restaurants are following the rule.

Similar mistakes: other brand pitfalls to watch for

Many brands include punctuation or nonstandard capitalization. Learn each brand's official styling and apply the same care you use for McDonald's.

Chick-fil-A - keep hyphen and caps. Wrong: Chickfila or Chick Fil A.
KFC - use initials without periods. Wrong: K.F.C.
Burger King - two words, no apostrophe. Use "Burger King's menu" for possession.
Starbucks - one word, no apostrophe. Wrong: Star Bucks.
