کرامیه فرقهای اسلامی بود که طی قرون ۱۰ تا ۱۳ میلادی در خراسان، با مرکزیت فکری نیشابور، پیروانی فراوان یافت. سردمدار این فرقه ابو عبدالله محمد بن کرام بود. کرامیان به خاطر اعتقاداتشان میان سایر فرق اسلامی بدنام و انگشتنما شدند. آنان معتقد بودند که ایمان جز اقرار و تصدیق زبانی (شهادتین) نیست. همچنین در مبحث خداشناسی معتقد به تجسیم بودند، یعنی برای خدا جسم و جهت قائل بودند و خدا را محل تمام حوادث میپنداشتند. تأکید بر ریاضتکشی در زندگی و مخالفت سرسختانه با مالکیت اقتصادی از دیگر ویژگیهای کرامیان بود.
Karramiyya (Arabic: كرّاميّه, romanized: Karrāmiyyah) was originally a Hanafi-Murji'ah sect in Islam which flourished in the central and eastern parts of the Islamic worlds, and especially in the Iranian regions, from the 9th century until the Mongol invasions in the 13th century.
The sect was founded by a Sistani named Abū ʿAbd Allāh Muḥammad b. Karrām (d. 896) who was a popular preacher in Khurasan in the 9th century in the vicinity of Nishapur. He later emigrated with many of his followers to Jerusalem. According to him, the Karrāmites were also called the "followers of Abū'Abdallāh" (aṣḥāb Abī'Abdallāh) . . Its main distribution areas were in Greater Khorasan, Transoxiana and eastern peripheral areas of Iran. Early Ghaznavids and the early Ghurid dynasty granted the Karrāmīyan rulership. The most important center of the community remained until the end of the 11th century Nishapur. After its decline, the Karrāmīya survived only in Ghazni and Ghor in the area of today's Afghanistan.
The doctrine of the Karramiyya consisted of literalism and anthropomorphism. Ibn Karram considered that God was a substance and that He had a body (jism) finite in certain directions when He comes into contact with the Throne. This belief was rejected by orthodox Sunni Muslim scholars such as Ibn Hajar al-Haytami who stated that, "They believe that God is a body sitting on the Throne, touching it and resting on it, and then moves down every night during the last third of the night to the heavens, and then goes back to His place at dawn."
The Karramiyya also held the view that the world was eternal and that God's power was limited.
