贯休或贯休法师（832年－912年），字德隐，俗姓姜氏，兰溪人，是唐末至五代十国时期的和尚。

贯休出生于诗书官宦人家，七岁时便在和安寺出家。曾为吴越武肃王钱镠所重，贯休有诗贺之：“贵逼身来不自由，几年勤苦蹈林丘。满堂花醉三千客，一剑霜寒十四州。莱子衣裳宫锦窄，谢公篇咏绮霞羞。他年名上凌烟阁，岂羡当时万户侯”。钱镠传令贯休将“十四州”改为“四十州”，才许相见。贯休不肯改，说：“州亦难添，诗亦难改。闲云野鹤，何天不可飞耶！”遂拂袖而去。中和元年(881) ，离开江东，流亡到荆湘一带。中和四年左右，返婺州主持戒坛。

Guanxiu (simplified Chinese:贯休; traditional Chinese:贯休; pinyin:Guànxiū; Wade–Giles:Kuan-hsiu) was a celebrated Buddhist monk, painter, poet, and calligrapher. His greatest works date from the Five Dynasties and Ten Kingdoms period. The collapse of the central Tang government in 907, meant artists and craftsmen lost their most powerful patrons. The imperial tang court had inspired a golden age of literature and art at its apogee. The various provincial courts who claimed to represent a continuation of the tradition of Tang government also claimed continuity in the arts and culture. The state of the Former Shu had acted as the traditional western sanctuary ever since the Emperor Xuanzong had sought refuge there during the An Shi Rebellion in 755. By the collapse of the Tang Dynasty something like a miniature Tang court existed at Chengdu. Guanxiu arrived in chengdu in 901, and remained there until his death.
