The social media platform is testing new ways in which is can tackle cyberbullying, and has developed a new feature in which users can control who replies to their posts, or block replies entirely.
The company said: "We want to help people feel safe participating in the conversation on Twitter."
The firm has already launched a feature which allows its users to hide replies to their tweets, but this new feature will help users stop people from posting replies that need to be hidden in the first place.
According to BBC News, the new feature is set to be tested early this year, and will allow users to select from four different settings for replies.
The Global setting allows anyone to respond, the Group option allows replies from people the users follows or mentioned, Panel lets only the people mentioned reply, and Statement blocks all replies.
The news comes as social media companies are facing intense scrutiny over how they are dealing with harassment - which has led to firms and governments introducing measures to tackle the issue.
YouTube said in December last year that it will no longer allow videos that "maliciously insult someone" based on "protected attributes" such as race, gender identity or sexuality.
And Instagram has been testing a feature that will hide the number of likes on posts.
