Threads Hashtags and Topic Tags
Most popular #threads hashtags for Instagram, TikTok and YouTube Shorts. Select any tags and copy them.
Quick answer: Threads uses topic tags instead of traditional hashtags. You can add one topic to each post, and it can be a phrase with spaces rather than a single joined-up word. Pick the topic that best matches what the post is about. When you share the same idea on Instagram, you get up to 5 regular hashtags instead.

About #threads content
Threads went its own way with tagging. When you write a post, you can tap the # option or type # to attach a topic, and Threads limits you to one per post. Threads explained the choice directly: a single tag makes it easier for people who care about a topic to find posts about it. Topic tags can contain spaces and some special characters, so "Book Recommendations" or "Remote Work" work as written.
The composer may also suggest topics, including trending ones or topics related to your past posts. Because you only get one, the decision matters: choose the community you want the conversation to happen in, not the broadest word that fits.
Many people post on Threads and Instagram from the same account. The Instagram sets below match common Threads post types, and the Threads set shows the single-topic version.
Tips for tagging Threads posts
- Choose the specific community over the broad category. "Indie Game Dev" puts you in a smaller, more engaged conversation than "Gaming".
- Write for replies. Threads is conversation-first, so end with a real question; the topic helps people find the post, replies keep it moving.
- Do not type a string of hashtags in the text. Only one topic is attached, and a list of # words just clutters the post.
- Cross-posting to Instagram? Rebuild the tags as a five-tag set using the hashtag limit guide. See social media hashtags and X hashtags for other text-first platforms.
Hashtags to avoid
| Hashtag | Why skip it |
|---|---|
#threadsviral | With only one topic slot, a reach word wastes the one signal you get. |
#followforfollow | Engagement-bait on any platform; on Threads it would replace a real topic. |
#threadsapp | Naming the app you are already on gives the post no subject. |

#threads hashtag FAQs
Does Threads use hashtags?
Threads uses topic tags, which work like a single hashtag attached to a post. You can add one per post, and it can contain spaces.
Why can I only add one tag on Threads?
Threads has said the one-tag limit makes it easier for people interested in a topic to find posts about it. It also stops posts from being stuffed with unrelated tags.
Do topic tags increase reach on Threads?
They help Threads understand the subject and let people browse a topic, which can widen reach. Replies and early engagement are likely to matter more than the tag itself.
