March Hashtags for Social Media – Over 190 Hashtags for 2025

If you’re looking for some of the most popular March hashtags for social media – or need help creating content for your social media channels– we’ve got you covered. 

From trending and popular hashtags to easy-to-rank hashtags, we’ve got everything you need to get your content found and grow your following on social media.

With the month of St. Patrick’s Day right around the corner, it’s time to start thinking about which hashtags to use on your social media calendar.

To help you out, we’ve compiled a list of over 190 hashtags for the March holidays and events that you can use on Instagram, Twitter, Facebook, and more.

From festive and popular Instagram hashtags like #happystpatricksday and #womenshistorymonth to more weather-related ones like #hellospring, there’s a hashtag for every occasion in March.

So whether you’re posting about March Madness or sharing a Spring promotion, be sure to use one (or more) of these hashtags to get your status updates seen by more people.

Or, if you’re running a promotion or contest, you can use hashtags like #contest or #giveaway to increase engagement.

Important Social Media Marketing Tips:

Hashtags are an outstanding way to increase the visibility and reach of your social media posts. 

You can use up to 30 hashtags in your Instagram posts, but research from Track Maven suggests 9 hashtags is the magic number for Instagram.

On Facebook and Twitter, I recommend you use 1 – 2 hashtags, and on LinkedIn, use 3 – 5 hashtags.

When compiling your list of hashtags for Instagram, be careful not to use only the most popular hashtags.

Hashtags with millions of posts are highly competitive, and the chances of your content being seen are much smaller.

That’s why I’ve curated a list of popular hashtags that range from 15,000 to 1 million posts or more.

Use a variety of these hashtags in your posts for maximum results.

Daily Social Media Hashtags

When compiling your list of hashtags to use for a status update, also remember to incorporate daily hashtags.

Daily hashtags are very popular, and they’re meant to be used on specific days of the week. 

I recommend using 1 – 2 daily hashtags in addition to your monthly, event, or promotion-specific hashtags.

Below are some of the most popular daily hashtags to use on social media.
