The association said this change “reflects its new identity” after it merged with the investment affairs sector of the Association of British Insurers (ABI) last summer.
The partial merger was designed to cover the “full spectrum” of investment management activity.
Chief executive of The Investment Association Daniel Godfrey said: “Our name has changed, but our purpose has not.
“The association exists to make investment better. Better for clients, so they achieve their financial goals. Better for companies, so they get the capital they need to grow. Better for the economy, so everyone prospers.”
Members’ assets stand at £5trn, making up 35% of all the assets managed throughout Europe.
The renamed organisation also represents around 85% of investment management in the UK, acting as a voice between shareholders and the companies in which they invest.
