When are sir and madam (and the contraction ma’am) capitalized? The answer depends on how you use them.

When to capitalize
Sir and madam are capitalized:

  • when beginning a letter/email
  • as an honorific coming before a name

Example: Dear Sir or Madam, I am writing to inform you that you a related to a Nigerian prince.
Example: My aunt was lucky enough to see Sir Paul McCartney play in the 1960s.

Note, however, that when referring to a man who has been given the honorific sir (or a woman who has become a dame) without using their full name (when sir or dame stands alone), it is not capitalized.

Example: My aunt was lucky enough to see Sir Paul McCartney play in the 1960s, before he became sir.

When to lowercase
Lowercase sir and madam in cases other than starting a correspondence and as an honorific before a name. This most concerns people who are writing dialogue in creative writing.

Example: “Please sir, may I have some more smores?” the boy asked hungrily.
Example: “It was a pleasure to meet you, madam,” the gentleman said.

To sum up
Capitalize sir and madam (and ma’am and dame) when starting a letter/email and when it comes before a name as an honorific. Lowercase sir and madam in other cases.
