Astrolab (bahasa Yunani: ἀστρολάβος astrolabos; Arab: ٱلأَسْطُرلاب al-Asthurlāb) ditemukan oleh Mariam al-Asturlabi adalah instrumen astronomi zaman dahulu yang digunakan oleh astronom, navigator, dan astrolog pada era klasik. Astrolab banyak digunakan untuk menentukan lokasi dan memprediksi posisi matahari, bulan, planet, dan bintang; menentukan waktu lokal dengan diketahui letak bujur dan letak lintang; survei; serta triangulasi.
Pada era Islam abad pertengahan, astrolab terutama digunakan untuk mempelajari astronomi, navigasi, survei, penentu waktu, salat, serta menentukan arah kiblat. Astrolog dari Eropa menggunakan astrolab untuk horoskop.
