Protesters or Protestors: Which Is Correct?

Updated 2026-10-12 · Which One Is Correct editorial team

Quick answer: The debate often centers on whether to use an s or an or at the end of the word, but you can rest easy knowing that both are accepted plurals. While protesters is the more common and preferred spelling in modern English, the version ending in or is still considered correct in certain regional dialects and by specific style guides.

The Short Answer

Both are accepted plurals, but protesters is the more common and preferred spelling.

People often confuse these forms because the word protest ends in an r, which makes the addition of another r or an or look identical in sound. This phonetic similarity causes writers to alternate between the two, even though standard usage favors the s ending for the majority of cases today.
