Most people believe the over-50s find it harder to get work than young jobseekeers, according to a new study.
A survey of 2,200 adults found that most think older people have something positive to offer the economy.
The Prince's Initiative for Mature Enterprise, a charity aimed at helping the over-50s consider self-employment, said its research suggests there is a "strong perception" of prejudice in the workplace.
Spokesman Teresa Folkes said: "Conversations around unemployment tend to focus on the high number of young people without a job. While this is a terrible situation, we've got to remember that older people are suffering in the job market too.
"People over the age of 50 have a wealth of skills and experience to make a positive contribution to their local communities, as well as the wider economy, and we would like to see more efforts to support them get back to work."
A Department for Work and Pensions spokesman said: "We agree that the over 50s often have a wealth of experience to offer the workplace which is why we are working with organisations like the age action alliance to promote the benefits of employing older workers.
"Over 50s receive tailored support to help them into work through Jobcentre Plus - or to set up their own business through schemes such as the New Enterprise Allowance. Latest figures show an extra 187,000 people aged 50 to 64 in work over the past year."
