Is Good Night Capitalized?

Telling someone “good night” is a nice way of wishing them a peaceful evening or sleep. But knowing whether and when the phrase is capitalized is challenging.

So, Is Good Night Capitalized?

Generally, the phrase “good night” is not capitalized when used in a sentence.

However, the phrase “good night” is capitalized when used in an email exchange, especially when it is used as a salutation at the beginning of an email. Email salutations (Dear, Hi, Hello, etc.) are capitalized anyways and “good night” is no exception. The same would apply for “good morning.”

Examples of Using Good Night

“Good Night, Mr. Kim!” said Jack as he was leaving work. It had been a great day at work and would be a good night. Before he went to sleep, he texted his wife, who was away on a business trip, and said “Good Night!” 

In the paragraph above, all three examples of the phrase “good night” were used. When Jack leaves the office he says goodbye to his boss so “good night” is capitalized. In the next sentence, the phrase is used generically in a sentence so it is not capitalized. Finally, in the text, Jack once again uses “good night” as a salutation so it is capitalized.
