Objective To describe the perception of caregivers of children with cerebral palsy (CP) concerning social support received and to verify how the characteristics of the children (i.e. type of CP and severity of motor impairment) and those of their caregivers (i.e. age, level of education, occupation, income and number of children) are significantly related to this perception. Method A total of 50 children with CP aged between 3 and 12 years and their respective caregivers participated in this study. Children were grouped in terms of type of CP and according to the severity of motor impairment through the Gross Motor Function Classification System (GMFCS). The Social Support Questionnaire (SSQ) was used to evaluate the perception of caregivers concerning the social support they receive (number of people offering support – SSQ‐N index, and level of satisfaction concerning such support – SSQ‐S index). Results The caregivers reported receiving support from a mean of 1.67 people. Core and extended family members (i.e. husband, mother, siblings) and friends are the most common providers of support. In regard to level of satisfaction, caregivers considered the support they received to be positive, obtaining a mean of 5.52 out of a total of six points. Children's and caregivers' characteristics were not significantly related to the SSQ‐N and SSQ‐S indexes. Conclusion Family members are the caregivers' primary source of social support and caregivers reported being satisfied with the support they received.
