Can you buy disability insurance if you're retired?

Disability insurance protects a person's ability to work and earn an income. If a person is already retired, than they are no longer working or earning an income, which leaves no income to insure.

In retirement there is a type of coverage called Long-Term Care insurance, which should be considered instead. This type of coverage is very similar to disability insurance, only rather than protecting one's ability to work and earn an income, it protects a person's assets and savings. It shifts the risk of having to pay for long-term care from the individual to the insurance company.
