বৃহৎ প্ৰবাল প্ৰাচীৰ (ইংৰাজী: Great Barrier Reef) হৈছে ২,৯০০ গাইগুটিয়া প্ৰবাল প্ৰাচীৰ আৰু ৯০০ দ্বীপেৰে গঠিত বিশ্বৰ সৰ্ববৃহৎ প্ৰবাল প্ৰাচীৰৰ শৃংখল।^[1]^[2]^[3] এই শৃংখলটোৰ কালি প্ৰায় ৩,৪৪,৪০০ বৰ্গ কি.মি. (3.444×10¹¹ বৰ্গ মিটাৰ)।^[4]^[5] এই সাগৰ অষ্ট্ৰেলিয়াৰ কুইনছলেণ্ডৰ প্ৰবাল সাগৰ (Coral Sea)-ত অৱস্থিত।

বৃহৎ প্ৰবাল প্ৰাচীৰ মহাকাশৰ পৰাও দেখা পোৱা যায়। জীৱৰ দ্বাৰা নিৰ্মিত ইয়েই বিশ্বৰ সৰ্ববৃহৎ আকাৰ।^[6] এই প্ৰবাল প্ৰাচীৰসমূহ লাখ লাখ প্ৰবাল পলিপ (coral polyps) নামৰ ক্ষুদ্ৰাকৃতিৰ জীৱই গঠন কৰিছে।^[7] এই প্ৰাচীৰসমূহ জৈববৈচিত্ৰ্যৰ দিশৰ পৰা অতি চহকী। ১৯৮১ চনত এই প্ৰাচীৰসমুহক ৱৰ্ল্ড হেৰিটেজ ছাইটৰ মৰ্য্যদা প্ৰদান কৰা হয়।^[1]^[2] বিশ্বৰ প্ৰাকৃতিক আশ্চৰ্য্যসমূহৰ ভিতৰত ইয়ো অন্যতম।^[8]^[9]

এই প্ৰবাল প্ৰাচীৰৰ এক বৃহৎ অংশ Great Barrier Reef Marine Park-ৰ অন্তৰ্ভুক্ত আৰু সংৰক্ষিত।

বৃহৎ প্ৰবাল প্ৰাচীৰসমুহে সন্মুখীন হোৱা ভাবুকি সমূহৰ ভিতৰত অত্যধিক মাছ ধৰা, পৰ্য্যটন, জলবায়ু পৰিবৰ্তন আদিয়ে প্ৰধান। ২০১২ চনত প্ৰকাশিত এক গৱেষণাৰ তথ্য অনুসৰি ১৯৮৫ চনৰ পৰা সেইসময়লৈ এই প্ৰাচীৰৰ কালি আধালৈ হ্ৰাস পাইছে।^[10]
