The Screaming Orphans, a pop-rock band from Ireland featuring four sisters, will perform at the Newport Waterfront Irish Festival on Saturday and Sunday.

Get your Irish up. If you need some Celtic provocation, you’re in luck.

The 11th annual Newport Waterfront Irish Festival is this weekend, offering all things Irish, and lots of them: food, beer, clothing, crafts and, most of all, music.

The festival, which is Saturday through Monday and takes place at the Newport Yachting Center, involves scores of vendors and dozens of performers on five stages over the three days.

“It’s a big site,” says Mike Martin, the festival’s director. “We have a nice blend of not only musical entertainment but comedy and dance.”

If you’ve really got the luck of the Irish, you’ll not only feel like you’re in Ireland, you’ll be on your way there. Every adult who purchases a ticket to the festival will be entered in a raffle for a five-day trip to Ireland. But the odds aren’t good. The festival is very popular, drawing 15,000 to 20,000 visitors.

Obviously there’s something appealing about Irish culture.

Perhaps it’s the whiskey, Irish cream or beer. The festival features the Guinness Beer Garden, which offers free interactive demonstrations: Pour Your Own Pint.

Or the draw could be the food: bangers, fish and chips, fried oysters, and corned beef and cabbage.

But no, the overwhelming feature of the festival is music.

“What has put us on the map over the years is the caliber of our musical entertainment. We’ve got big-name national and international names at our site. But we haven’t lost the roots of the festival, which is really a community event.”

The festival involves several headlining performers.

Eileen Ivers is a nine-time fiddle champion of Ireland, a founding member of the group Cherish the Ladies and is probably best known for her performances with the stage show Riverdance.

Black 47, a six-member band from Ireland that takes its name from 1847, the worst year of Ireland’s Potato Famine, presents traditional Irish melodies mixed with rock, reggae, jazz and hip-hop.

Aoife Clancy performs traditional Irish song and contemporary folk music, and has soloed with the Boston Pops.

The Screaming Orphans are a pop-rock band from Ireland featuring four sisters.

The Makem Brothers and Spain Brothers involves the three sons of the late, great master of Irish music Tommy Makem combining forces with Liam and Mickey Spain of New Hampshire.

The Glengarry Bhoys aren’t Irish, though they can sound a little like it. And they’re not all boys. One member’s a woman. The group, from Canada, plays the music of Canadian Highland Scots and French-Canadians.

For a little Celtic comedy, the Tartan Terrors mix Irish music and dance with humor.

There will also be Irish step dancing, and a children’s area with arts and crafts and a man who makes sculptures with balloons.

The Newport Waterfront Irish Festival opens each day at 11 a.m., and closes Saturday at 9 p.m., Sunday at 8 p.m. and Monday at 6 p.m. Tickets are $15, $12 for seniors and children 12-17, and free for those younger. On Monday, college students will be admitted for $12. The Newport Yachting Center is located on America’s Cup Avenue. For more information, visit www.newportirishfestival.com or call (401) 846-1600.
