Andrew Graham (8 April 1815 – 5 November 1908) adalah seorang astronom dan ahli hitung asal Irlandia.[1][2]

Dia menemukan asteroid 9 Metis pada tahun 1848 saat dia masih bekerja di Observatorium Markree di Sligo, Irlandia. Kemudian ia bekerja di Markree Catalogue, yang memuat sekitar enam puluh ribu pengamatan bintang beserta ekliptika yang diambil antara 8 Agustus 1848 dan 27 Maret 1856 yang diterbitkan menjadi empat volume secara berurutan pada tahun 1851, 1853, 1854, dan 1856. Saat mengerjakan hal ini, dia juga mengembangkan mikrometer square-bar, yang sangat meningkatkan efisiensi dalam menentukan posisi asensio rekta dan deklinasi dari benda-benda langit.

Kemudian dia bekerja sebagai Asisten Pertama di Observatorium Cambridge, Inggris dari tahun 1864 hingga 1904 di mana dia mengerjakan Cambridge Catalogue, penambahan dari hasil karya sebelumnya di Markee (kecuali bintang zona selatan), yang diterbitkan pada tahun 1897.
