洛夫克拉夫特於1890年8月20日早上9点出生在美國普罗维登斯安格爾街(英语:Angell Street)194号(现454号)的家宅里。他是珠宝推销员温菲尔德·斯科特·洛夫克拉夫特(Winfield Scott Lovecraft)与其妻莎拉·苏珊·菲利普斯·洛夫克拉夫特(Sarah Susan Phillips Lovecraft)的獨生子。可追溯到的母系祖先于1630年抵达马萨诸塞湾殖民地。他的父母在30岁左右才成婚,且双方都是初次结婚,这在当时并不常见。1893年,洛夫克拉夫特三岁时,他的父亲在推销旅行途中於芝加哥的一家旅馆精神失常,其后被送往普罗维登斯的巴特勒医院;老洛夫克拉夫特在那里一直待到1898年过世。洛夫克拉夫特一生都坚称父亲发疯的原因是工作过度引起的“神经衰弱”,但是现代观点认为其父失常的真正原因是麻痹性痴呆[6]。洛夫克拉夫特到底是否了解父亲的疾病及其真正成因(梅毒),今天已无从稽考,但他的母亲很可能曾使用过含砷的酊剂(当时治疗梅毒的常用药物)作为“预防药物”。
在父亲住院后,洛夫克拉夫特由母亲、两个姨母(莉莉安·德萝拉·菲利普斯与安妮·埃米丽妮·菲利普斯,Lillian Delora Phillips & Annie Emeline Phillips)以及商人外祖父惠普尔·范·布伦·菲利普斯(Whipple Van Buren Phillips)照看,五人住在一间屋子里。洛夫克拉夫特小时候就表现出与众不同的文學天赋,他三岁时即能背诵诗歌,六岁时已能写出完整的诗篇。他的外祖父经常給他一些文学经典鼓励他阅读(如《一千零一夜》,布尔芬奇的《神话时代》,还有儿童版本的《伊利亚特》与《奥德赛》)。他的外祖父也時常向洛夫克拉夫特讲述一些自编的哥特式恐怖故事,這引起了他对怪奇小说的兴趣。不过,洛夫克拉夫特的母亲时常担心这些故事会给他带来不良影响。
洛夫克拉夫特童年时经常患病,虽然他总是将原因歸咎于自己身体孱弱,但其中有一些疾病可以肯定为心身疾病。早前的猜测认为他在胎儿时从父母处感染了梅毒,但这种看法现已被摒弃。由于身体状况和好斗的天性,洛夫克拉夫特在八岁前基本没有接受过学校教育,八岁时入学一年后又旋即退学。这一时期他广泛地阅读各类书籍,对化学和天文学展现了浓厚的兴趣。他於1899年起自己編輯出版了几期胶版印刷刊物《科学公报》(The Scientific Gazette)。四年后,他進入當地的霍普街高中(英语:Hope High School (Rhode Island)))就读。一般认为洛夫克拉夫特早年患有夜驚(一种睡眠疾病);他相信自己曾被恐怖的“暗夜幽灵”袭击过。他很多作品的灵感可能都来自于这一时期受到的惊吓。
母亲去世后数月,洛夫克拉夫特前往波士顿参加一次业余记者集会,会上他遇見了索尼娅·格林。索尼娅出生于1883年,比洛夫克拉夫特年长7岁,她的祖先是乌克兰裔犹太人。两人於1924年结婚,婚后移居至纽约布鲁克林。洛夫克拉夫特的姨母們对这场婚姻不甚满意,因为她们不希望洛夫克拉夫特娶一个商人为妻(索尼娅开有一间帽店)。婚姻伊始,洛夫克拉夫特被纽约的生活彻底迷住,但很快夫妇两人就遇到了财务危机。索尼娅变卖了帽店,其後又出现了健康问题。由於洛夫克拉夫特的薪水不足供两人開銷,他的妻子不得不搬到克利夫兰求职。此后洛夫克拉夫特独自一人住在布鲁克林的雷德胡克社区,逐渐对纽约生活起了厌恶之情[7]。而在移民大潮中无法找到任何工作这一严峻的现实,与他對自身盎格魯-撒克遜人血統的認同相抵触,這激起了他的种族主义观点,具體体现在了他的短篇故事《雷德胡克恐怖事件(英语:The Horror at Red Hook)》(The Horror at Red Hook)之中[8]。
洛夫克拉夫特和他父母一起葬於菲利普斯家族墓地。1977年,他的一个读者团体出资为他在天鹅角(Swan Point)重修了一座坟墓,墓碑上刻了洛夫克拉夫特的姓名、出生与死亡日期,以及一句话:“I AM PROVIDENCE”(雙關語,可译为“我是普罗维登斯人”或“吾乃天命之人”),这句话出自他的私人信件。
