- Doctor's appointment is more common and usually sounds more natural.

The Quick Answer
You can say both doctor's appointment and doctor appointment. Both are acceptable. But in everyday English, doctor's appointment is the phrase most learners should choose because it sounds more natural to most speakers.
The important point is this: the apostrophe 's does not always mean simple ownership. It can also show that one noun is connected with another noun.

Why Does the Apostrophe Work Here?
In phrases like doctor's appointment, the apostrophe shows connection or description. The appointment is connected with a doctor. English has many patterns like this.
teacher's meeting
A meeting connected with a teacher or teachers.
children's books
Books for children, not books owned by children.
women's clinic
A clinic for women or related to women’s health.
driver's licence
A licence for driving, not a licence owned by one driver.
school bus
A bus connected with school; no apostrophe is needed.
business meeting
A meeting connected with business; business works like an adjective.
English also uses nouns before nouns: school bus, business meeting, language class. This is why “doctor appointment” can work too. It uses “doctor” like a describing word.
Common Mistakes to Avoid
Too literal
A doctor's appointment does not mean the doctor owns the appointment.
Think “appointment connected with a doctor.”
Over-correction
Do not tell people “doctor appointment” is the only correct form.
Doctor's appointment is very common and correct.
Apostrophe confusion
Do not write doctors appointment in careful writing.
Use doctor's appointment or doctor appointment.
Wrong plural logic
If you mean one visit, do not write doctors' appointment.
Use doctor's appointment.
Mini Practice
Choose the most natural sentence:
A. I have a doctor's appointment tomorrow.
B. I have doctors appointment tomorrow.
