Established in 18 August 1969 by 13 young watercolour enthusiasts, the Singapore Watercolour Society (SWS) is the only non-profit art organisation in Singapore that focuses on the art of watercolour painting. With the ever-increasing membership of more than 150 artists, the society holds its annual exhibitions in September each year. Members also get together for outdoor/plein air painting sessions every week and the society organises overseas painting trips regularly.
成立于1969年8月18日，新加坡水彩画会是本地唯一一个专研及推广水彩为绘画媒介的非营利组织。现今拥有超过150名会员，除了在每年的9月份举办常年性的美展外，每一周会员们也会相约在岛国的其中一角，进行户外写生活动。水彩画会也经常组团出国采风，例如邻国马来西亚石耕庄和沙捞越古晋等。画会也积极参与国内外的大型展出，例如仁川国际联展、印尼国际水彩画会联展等。
Since its establishment, SWS has organised and participated in major exhibitions in Singapore and abroad. As part of our community outreach, we have initiated the National Junior Watercolour Competition to generate interest in watercolour painting amongst the younger generation. Students from the main stream schools are invited, and winners are given cash awards and certificates. A special pre-competition workshop is also organised to prepare the young participants for the competition. In conjunction with SG50 Jubilee Celebration, SWS has partnered with Lianhe Zaobao, the main Chinese daily, to provide a painting every week to complement their special weekly write-up on the historical places of Singapore, for the whole of year 2015.
在社区文化方面，新加坡水彩画会每年都会举行全国性的青少年水彩现场绘画比赛。此活动邀请新加坡的各个学府，希望把水彩绘画的精神传承给新一代的小画家们。比赛前的一个星期，水彩画会成员们也会为参与的学生们举办水彩示范。学生们能获得的不只是现金奖及证书，更多的是水彩写生以及现场绘画比赛的经验。
2015年，新加坡欢庆金禧年，水彩画会更是和新加坡联合早报携手合作，推出为期一年的金禧年专栏。每周的星期一，该专栏会介绍一个新加坡著名的地标或是鲜为人知的地方，由一名水彩画会的会员以水彩媒个画出该地方的历史背景，图文并茂的为读者们介绍新加坡的大街小巷,为期五十周。
Our honorary President, Ong Kim Seng put Singapore onto the watercolour world map when he became the first Asian outside of United States to be awarded signature membership of the American Watercolor Society (AWS) in 1990 and became a Dolphin Fellow of AWS in 2000. His achievements pave the way for other Singaporean artists to venture outside of the island nation and today many members of SWS have won major awards and getting juried into international shows throughout the world.
1990年，新加坡水彩画会荣誉会长王金成先生成为第一位美国以外被颁发美国水彩协会特色会员证的亚洲水彩画家，2000年更获海豚研究员奖章，他把新加坡的水彩创作跻身到世界版图里。王金成先生的成功，给新加坡水彩画家们打了一剂强心针，证明小红点也能培幕出画家，也能站上国际舞台上。确实如此，这二十几年来越来越多的新加坡水彩画家纷纷受到国际水彩界的关注与认同。
In 1997, SWS moved its premises to Telok Kurau Studios. SWS has been operating from TKS ever since with many visiting artists came to give talks, demo and workshops.
