I think St. Patrick’s Day is one of the most fun holiday celebrations, right up there with Mardi Gras! It’s a time to throw a party just for the pure pleasure of having food & cocktails with friends, and it’s acceptable to get a little ‘cheeky’ with decorations and details!  

Celebrate the luck of the Irish on March 17 or plan a party for the Saturday before or after the actual date so that guests can recover the next day.

I’ve put together some ideas that you can implement for your own adult theme party at home. With lots of green, rainbows, and a “pot of gold” your guests are sure to have a good time.

Fun Party Ideas

Send digital invitations about 3 weeks ahead. This is a casual holiday so there’s no need to send paper invites through the mail.

Dress for the theme. This is one theme party where guests will want to dress for the occasion, and there’s lots of leeway. Go over the top with rainbow colors, leprecaun hats, and green and gold beaded necklaces, or keep it simple with a stylish green or gold outfit.

Set up a photo booth with props and a backdrop. Have leprechaun hats, funny glasses, and green or red hair wigs. Hang green curtains for a backdrop, or a streamer rainbow.

Do a pub crawl at home or on your neighborhood block.

  • Set up a few different areas or rooms in your home where guests can visit. Each one has a different food and drink pairing. For example, serve Guinness and fish n’ chips in the dining room, have green jello shots with mini Reuben sandwiches in the kitchen, and have Irish coffee with green cupcakes in the living room. Or, serve a different Irish beer in each space.
  • This idea works great for a neighborhood block party too. Just follow the same idea, going from house to house. Don’t drink and drive, though!

Host an Irish Whiskey tasting and include some of the popular Irish brands like Jameson, Bushmills, and Paddy.

Relive your college days and play beer pong.

Keep it classy with an Irish themed dinner party.

Play the Lucky Number game for fun prizes. The number 7 is lucky for St. Patricks day. Add it to a grab bag to see who draws the lucky number. You can have several in the bag or do several rounds. Give out silly gifts like shot glass necklaces or gold coin chocolates.

Have a scavenger hunt to “find the leprechaun” or the “pot of gold.” This takes some pre-planning but it’s a terrific idea for a neighborhood party.

Play some Irish trivia games. You can create questions by doing a simple web search or using Wikipedia to curate fun facts.

Make a playlist of Irish bands. Some of the most popular ones are U2, The Cranberries, Flogging Molly, Van Morrison, The Strypes, the Dubliners, Clannad, the Corrs, Boomtown Rats, Westlife, Snow Patrol, Hozier, Celtic Women. 

Learn how to Riverdance or dance an Irish jig. Have a contest to see who can do it the best, or funniest.

Decorate with green table cloth, and gold coins. Here’s how to incorporate the coins in creative ways.

  • Scatter the coins down the center like a table runner.
  • Fill different sizes and shapes of clear jars and bowls with the gold coins.
  • Put the coins in small pots down the center of the table.

Use turf grass as a table cover to mimic the rolling green hills of the Emerald Coast and Irish countryside.
