From beach outings to pool parties, parades and other Memorial Day remembrance events, to firing up the grill and spending time with friends and family, we want to see your photos.

Share them here, or on Twitter and Instagram using the hashtag #MemorialDayLI.

Looking for weekend ideas? You'll find plenty of great things to do around Long Island in our Memorial Day guide.
