Autistic masking refers to the phenomenon in which individuals with autism spectrum disorder (ASD) attempt to hide or suppress their autistic traits in order to fit in with their neurotypical peers or to avoid negative social consequences. This can involve using compensatory strategies such as copying the behaviors of others, avoiding eye contact, or pretending to understand social cues. Autistic masking is often referred to as "camouflaging" because it involves attempting to blend in with the neurotypical population.

It is important to note that autistic masking is not the same as "high-functioning" autism. While some individuals with ASD may be able to mask their autistic traits in certain situations, this does not necessarily mean that they experience fewer challenges or difficulties related to their autism. Autistic masking can be physically and emotionally exhausting for individuals with ASD, and may contribute to feelings of distress, anxiety, and depression.
