After you’ve marched — or stumbled — up Fifth Avenue from Midtown to 86th Street in the annual St. Patrick’s Day Parade, you’ll find plenty to do to keep your Irish eyes smiling. Whether it’s bagpipes, leprechauns or getting fluthered (that’s drunk in Dublinese), New Yorkers looking to celebrate St. Patrick’s Day have the luck of the Irish on their side. Gather your shamrock-covered friends and check out any of these spirited events.

BELLY UP TO THE GUINNESS: Paddy Reilly’s (519 Second Ave.; 212-686-1210, paddyreillysmusicbar.us)

The self-proclaimed world’s first and only all-draft Guinness bar — all eight of the bar’s taps serve the Irish beer — draws people from all over, says manager Steve Duggan. “People come from Connecticut, Long Island, The Bronx to get a good pint of Guinness, because it’s hard to get a good pint of Guinness anywhere.” But there’s more than stout beer here. Beginning at 1 p.m., three Irish bands — Irish Trad Session, Beware of the Pig and the Mickey Finns — will play into the wee hours.

CRAWL, DON’T WALK: The Luck of the Irish Saint Paddy’s Day Pub Crawl (212-724-3900, iadventure.com; tickets $20 to $85)

To prepare for a day of boozing, start with the Green Breakfast of Champions, 8 a.m. to noon, at SideBAR (118 E. 15th St.) or Village Pourhouse Downtown (64 Third Ave.). For $20 you can feast on Lucky Charms, green eggs, green pancakes and green bagels — as well as green beer to wash it down. Check in at either of these places, or one of the other 175 watering holes taking part in the pub crawl, which gets you a map of venues, a cup, wristband and drink specials. (Times vary, but at Pourhouse, the beer flows at 10 a.m.)

“People are dressed head to toe in green with shamrock necklaces and green glasses and huge green top hats,” says Erika London, an exec with pub-crawl organizer iadventure. “It’s a big dance party.” Several venues will have DJs or live music playing a mix of Irish music and Top 40 hits. Then, if you’re up for more decadence, do it again tomorrow for the Hangover Pub Crawl!

PARTY ON THE WATER: The Luck of the Irish Aboard the Jewel Yacht (212-600-9297,oncruises.com; admission $25, cash bar)

Hang out with your shamrock-antenna-wearing cohorts while taking in some of the best views of Manhattan aboard the Jewel Yacht for the “Luck of the Irish” cruise, 8 to 11 p.m. A DJ will spin Top 40 hits as you sail around New York Harbor. Board at Skyport Marina, 23rd Street and FDR Drive.

LOW-KEY LOUNGE:R Lounge in the Renaissance Times Square (714 Seventh Ave.; 212-261-5200, rloungetimessquare.com)

Ditch the boiled corned beef-and-cabbage dishes that every other New York eatery will be serving and try the R Lounge’s fresh take. Senior sous chef Stephen Christensen will serve a Reuben flatbread with corned beef, Gruyere, sauerkraut and Russian aioli ($12), along with a red cabbage and potato soup ($10). Not a green-beer person? How about the Green Lady ($12), a mix of Leblon Cachaca, Midori, sour mix, pineapple juice and sage.

IRISH FUN FOR ALL AGES: Go Burger (1448 Second Ave.; 212-988-9822)

For a Celtic twist, this usually family-friendly eatery is serving a boozy “Kiss Me I’m Irish” shake ($12): Guinness, Baileys and Jameson mixed with vanilla and coffee ice cream, whipped cream, shamrock sprinkles and a green shamrock cookie. “It is just killer,” says general manager Chris Romano. Nonalcoholic versions swap in green pistachio ice cream for the kiddies. Go Burger will also slather Irish cheddar, sauerkraut and corned beef on top of its signature sandwich (ground beef, melted cheese and onions between rye bread slices) in its “St. Patty Melt” ($14).

BANGERS AND (GREEN) BEER: Whiskey Park (100 Central Park South; 212-307-9222)

Instead of offering the usual nachos and wings, this sports bar turned to Todd English’s Food Hall to create traditional Irish comfort food. “We’ve got beer bangers [$14], which sound like a lot of fun,” says Vinny Mauriello, managing partner for owner Gerber Group. They also have shaved corned beef sandwiches ($14), corned beef brisket ($24) and chocolate stout curly cake ($7), as well as Jameson drink specials ($9) and green draft beer ($6). Maybe you’ll catch an impromptu performance by the NYPD Pipes and Drums when they stop by after the parade. Plus, there will be multiple T-shirt giveaways throughout the day.

*The Chieftains featuring Paddy Moloney (Carnegie Hall, 881 Seventh Ave.; 212-247-7800, carnegiehall.com; tickets start at $29; 8 p.m.): Celebrating their 50th anniversary, Ireland’s official music ambassadors, who have performed at the hallowed hall on St. Pat’s Day more than a dozen times, will perform traditional Irish music.

*IRISH FEST (Webster Hall, 125 E. 11th St.; 212-353-1600, nycirishfest.com; $20 and up; noon): Festivities include two Irish bands, a bagpiper troupe, leprechauns (or people dressed as leprechauns), Irish fare, a variety of beers and the Ireland-versus-England rugby match on TV.

*ST. PATRICK’S DAY SOIREE WITH JOE HURLEY (Joe’s Pub, 425 Lafayette St.;212-539-8778, joespub.com; $20; 11:30 p.m.): The singer-songwriter presents “My Wild Irish Roses,” with special guests including Michael Cerveris, Laura Cantrell and Ellen Foley. They’ll perform “Irish ballads, singalongs and rabble rousers.” In other words, a lot of cool covers.
