هي لغة برمجة وظيفية مفتوحة المصدر صُممت للمرة الأولى عام 1990، وحملت تسمية هاسكل نسبة لهاسكل بروكس كاري، عالم الرياضيات والمنطق المشهور بإنشاء المنطق التوافقي.
تعود أهمية لغة برمجة هاسكل لأنها تُستخدم في التطبيقات الصناعية، إذ تتمتع ببنية قوية بحيث تتألف من دوال للتنفيذ. تتميز بأنها موثوقة وتزيد من إنتاجية المبرمجين لأنها تُكتب بشيفرات برمجية أقصر قابلة للتصحيح.
يوجد العديد من المزايا للغة برمجة هاسكل، تعرّف عليها:
يوجد العديد من الشركات التي تستخدم لغة هاسكل في أعمالها ومن أشهرها:
