Miami-Dade

The county name is officially Miami-Dade - with a hyphen. Many writers drop the hyphen (Miami Dade), which looks minor but is incorrect in most formal and public uses.

Below: the rule, quick checks, many wrong/right pairs, and ready-to-paste rewrites for work, school, and casual contexts.

Quick answer

Always write Miami-Dade with a hyphen when referring to the county or any official entity that uses that name.

Correct: Miami-Dade
Incorrect: Miami Dade
If you cite a specific organization, match its spelling - for the county that means Miami-Dade.

Core explanation: official form and why it matters

Miami-Dade is the county's official, hyphenated name. The hyphen is part of the established form, so keeping it avoids inconsistent styling and factual ambiguity in official, journalistic, and legal contexts.

Treat the full form as a fixed unit: capitalize both parts and keep the hyphen.

Rule: Use Miami-Dade whenever you mean the county or an entity named after the county.
Wrong: I filed my property tax in Miami Dade.
Right: I filed my property tax in Miami-Dade.

Hyphenation rules (quick reference)

If an official source hyphenates a place name, copy that form. For hyphenated place names, keep the hyphen in normal uses - in headlines, sentences, possessives, and adjectival forms.

If the county or government website uses a hyphen → use a hyphen.
Keep capitalization: Miami-Dade, not miami-dade or Miami-dade.
Usage: The Miami-Dade County website lists public services.
Usage: Treat similar cases the same way (for example, Winston-Salem).

Spacing, punctuation, and possessives

The hyphen stays when the name appears with commas, apostrophes, or as an adjective: Miami-Dade, Miami-Dade's, Miami-Dade-based. Don't insert spaces around the hyphen.

Correct: Miami-Dade, Miami-Dade's, Miami-Dade-based.
Incorrect: Miami - Dade, Miami -Dade, Miami Dade (with extra spacing).
Usage: Correct: Miami-Dade's budget was approved today.
Usage: Correct: The Miami-Dade-based nonprofit applied for the grant.

Real usage by context: work, school, and casual

Use Miami-Dade in work and formal documents. In school writing, follow the official form. Casual messages may omit the hyphen, but public posts and shared content should keep it.

Default to Miami-Dade in anything that might be published or shared.
Casual texts are forgiving, but use the hyphen in emails, resumes, and class papers.

Work - Incorrect: The Miami Dade Grants Office approved the budget.
Work - Correct: The Miami-Dade Grants Office approved the budget.
School - Incorrect: I attended a workshop hosted by Miami Dade College.
School - Correct: I attended a workshop hosted by Miami-Dade College.
Casual - Incorrect: Heading to Miami Dade for the weekend.
Casual - Correct: Heading to Miami-Dade for the weekend.

Memory trick and quick search-and-fix

Mnemonic: picture a bridge (the hyphen) connecting Miami and Dade - the bridge belongs in the name.

Fast fix: search your document for the two-word string "Miami Dade" and replace it with "Miami-Dade." Then scan contexts like possessives and adjectives to confirm no unintended changes.

If a publication intentionally drops it (rare), follow that house style; otherwise, keep the hyphen.
Tip: Use Find → 'Miami Dade' → Replace with 'Miami-Dade', then eyeball each instance.

Similar mistakes and grammar edge cases

Place-name conventions vary: Winston-Salem is hyphenated, St. Louis uses an abbreviation and space. When unsure, check an authoritative source.

If an organization brands itself without the hyphen, reproduce that brand form when referring to the organization, but use Miami-Dade for the county and official entities.

Don't conflate the city "Miami" with "Miami-Dade" (county).
In headlines, possessives, and adjectival uses, keep the hyphen unless a publication's style guide says otherwise.
Edge: Brand exception - a private company may style itself as "Miami Dade Bikes." Cite the brand exactly, but use Miami-Dade for county references.
