The president will surely don a green tie; the Chicago River will be dyed green; and South Boston natives will march in their famous parade.

If you are one of the estimated 33 million Americans of Irish heritage -- or among the countless more who appreciate a cold pint of Guinness -- you've got the date marked on your calendar: St. Patrick's Day, held annually on March 17, is only a few weeks away.

So it may be time to not only mentally prepare for the event but also get your (green) paraphernalia in order. And if you want to stand out from the crowd in Shamrock-covered hats, ties and T-shirts this year, why not change your iPhone cover for the occasion?

There are plenty of options to protect your smartphone and, in a unique way, honor Ireland's patron saint. Here are some of our favorites:

  • Who wouldn't a little love with that Guinness-induced happiness? And while the "Kiss me, I'm Irish" catchphrase may not be exactly avant-garde, it might seem downright clever after the third or fourth pint. Sunshine Design Cases offers the corresponding clear cover via Amazon, and at a price tag $15.99, you'll have plenty of dough left to buy a round for your friends.

  • If your past experiences tell you that all that beer on St. Patty's Day may lead you to act out a bit, consider preventative measures: You could hold your liquor or -- if that's not an option -- choose the "Leprechauns Make Me Do It" tough case available at CafePress. This good-natured cover will set you back $30.

  • You won't spend March 17 at a wine tasting, but you're still looking for something a little bit more classy? Take a look at Zazzle's Shamrock-inspired Celtic case, which the maker promises is form-fitting and featherlight. This cover comes with a striking design, but it's on the pricey side: $42.95 for your standard iPhone and $47.95 if you own the larger iPhone 6 Plus.

  • If you're truly Irish, chances are you're Bostonian, as well. And if you're Bostonian, you're a Red Sox Fan. Luckily, all those traditions combine rather neatly with the CandyShell case from Coveroo. It costs $42.95 with free shipping, and don't fret: Giants, Yankees, Cubs and Mets options are also available.
